| Integrated transportation and energy sector CO2 emission control strategies |
| Author: Henrik Lund and Ebbe Münster |
| Abstract:
The main topic of the article is the integration of the transport and
the energy sector in the case of Denmark. The article illustrates
and quantifies the mutual benefits of integrating strategies for
future energy and transport CO2 emissions control. Today, this
issue is very relevant in Denmark due to the high share of
fluctuating renewable energy produced in the country. In the
future, such issue will apply to other countries that plan to use a
high share of renewable energy. In short, the energy sector can
help the transport sector to replace oil by renewable energy and
CHP, while the transport sector can assist the energy system in
integrating a higher share of intermittent energy and CHP. Two
scenarios for partial conversion of the transport fleet have been
considered. One is battery cars combined with hydrogen fuel cell
cars, while the other is the use of biofuel (ethanol) and synthetic
fuel (methanol) for internal combustion cars. An increase in the
fraction of electricity delivered by fluctuating sources like wind
power will lead to excess electricity production, and the two
scenarios have a substantial effect on the decrease of the excess
production.

| Cogeneration of power & heat and cogeneration of power and desalinated water; modelling for optimal system performance |
| Author: Poul Alberg Østergaard |
| Abstract:
Cogeneration of heat & power and cogeneration of desalinated
water and power have similarities from an energy systems
perspective. Both introduce limitations in the freedom of action
but also introduce possibilities for integrating fluctuating
renewable energy sources. Through energy systems analyses, it
was demonstrated how storage tanks desalinated water could
introduce a buffer corresponding to heat storages for optimising
performance of energy systems with respect to integrating
fluctuating energy sources. |

| Comparison of Electricity Balancing for Large Scale Integration of Renewable Energy in six European Regions. |
| Author: Ebbe Münster |
| Abstract:
This paper address the question of balancing fluctuating
electricity productions from renewable energy sources in Europe
a) by the use of additional capacity of interregional transmission
lines versus b) by increasing the balancing capacity of the regional
production and distribution system. The aim has been to identify
technologies and in particular mix of technologies which will
enable the increase in fluctuating and unforeseeable electrical
productions which will be the result of the fulfilment of the
current EU energy plans. It is found that new transmission lines
often cannot compete economically with measures to improve the
internal balancing potential of the regions involved. Part of the
reason for this is the large costs and long planning periods
involved in the strengthening of the internal transmission
networks which are necessary to distribute the increased exports
and imports. The fundamental changes of the production and
distribution systems for electricity which are mainly caused by the
rapid development of the information technology and the
liberalisation of the markets are shown to have a positive potential
for the growing balancing requirements. The scenario analyses
have been carried out for the electrical production and
consumption systems in six regions in Denmark, Estonia,
Germany, Great Brittan, Spain, and Poland. |

| Energy Trader |
| Author: Ebbe Münster |
| Abstract:
Based on the findings of the Energy Camp 2005 an idea for a
system for optimal operation of household appliances, the Energy
Trader, was developed. The core of the idea is to make
information on online energy prices (eventually prognoses for
prices) available for a central unit in the house. This unit is also
able to communicate with all relevant appliances including
heating elements via Bluetooth or similar wireless protocols. If
mass production could bring the price for such systems down to
less than say 1000 they might be commercially relevant and
have important positive effects on the DSM capacity of the entire
distribution system. The idea need political support because it
relies on the necessary standards for communication to be
decided. |

| Optimal Design of Combined Heat and Power Plants Using Thermal Stores in the UK |
| Author: Aikaterini Fragaki, David Toke and Anders N. Andersen, |
| Abstract:
There has been discussion about the extent to which combined
heat and power (CHP) plants with thermal stores are suitable for
sustainable energy production and, under certain conditions, for
integration of wind energy. At the moment, in the UK the
development of this type of plant is limited. This paper analyses
the economics and optimum size of (CHP) operating with gas
engines and thermal stores in British market conditions assuming
that all electricity is exported to the public electricity supply. This
is achieved using energyPRO software. It is shown that, due to the
big differences in electricity prices between day and night, the use
of thermal stores could make the practice of exporting electricity
from CHP plant much more profitable in the UK. The optimal size
of CHP plant (exporting its electricity to the grid) for a district or
community heating load of 20000 MWh per year is found to be a
3MWe gas engine with a 7.8 MWh thermal store. In this case the
analysis reveals that the use of thermal store more than doubles
the return on investments (as measured in net present value). It is
concluded that thermal stores can improve the overall economics
of CHP plants in present British circumstances. |

| DESIRE UK - Summary of Interim Research Conclusions |
| Author: David Toke and Katerina Fragaki |
| Abstract:
The economic performance of community (and some industrial)
CHP will be considerably increased by the use of thermal stores.
Our modelling suggests that the optimum economic size in MWe
is increased by over 50 per cent for a given example. Moreover, if,
in addition to this, CHP units are `aggregated´ together to sell
power to the grid, the economic performance of the CHP units
will be further enhanced, and the optimum size of CHP plant
increased by even greater amounts. This activity depends on the
use of the thermal store system to sell exported power directly to
wholesale power markets through aggregated despatch. Moreover,
recent changes in planning policy guidance and incentives
inherent in new building regulations create great potential for
development of community heating and CHP in new building
developments. |

| Incentives for CHP Development in the UK |
| Author: Aikaterini Fragaki, Richard Green and David Toke |
| Abstract:
This will disseminate information concerning incentives available
to CHP in the UK compared to other countries. This article
assesses the impact of the UK government´s measures to promote
CHP schemes, the most important of which is exemption from the
Climate Change Levy (CCL), in support of its target for 2010 of
10,000 MWe of CHP generating capacity. This paper analyses the
effectiveness of this exemption in terms of its impact on key
investment parameters. It is shown that CCL exemption can
reduce quite significantly the simple pay back period for a CHP
project and has higher impact on the IRR compared to an
accelerated depreciation policy. |

| Wind power forecasting |
| Author: Bernhard Lange |
| Abstract:
The chapter explains the role wind power forecasting plays in
tackling the challenge of the fluctuating power output of wind
power. In the electricity system, supply and demand must be equal
at each time. Thus, in an electricity system with an important
share of wind power, new methods of balancing supply and
demand are needed. Therefore wind power forecasting is the
prerequisite for the integration of a large share of wind power in
an electricity system, as it links the weather dependent production
with the scheduled production of conventional power plants and
the forecast of the electricity demand, the latter being predictable
with reasonable accuracy. |

Virtual wind and cogeneration power plant (In Spanish: Central
virtual de energía eólica y cogeneración) |
| Author: Carlos Madina |
| Abstract:
The increase of electricity production from renewable energy
sources resulted, under certain circumstances, in some operational
problems in different countries for the system operator, due to the
lack of dispatch capacity of these technologies. Usually, installed
capacity and/or electricity output from these plants is limited, but
there is an alternative solution, which consists in the joint use of
renewable and non-renewable energy sources.
This paper presents the results from DESIRE project (contract
TREN/05/FP6EN/S07.43516/ 513473), which is funded by the
European Commission under the 6th Framework Programme, and
which analyses the joint use of wind power and Combined Heat
and Power (CHP) to create a Virtual Power Plant, whose output
can be dispatched.
The analysis carried out in the project demonstrates that these
virtual power plants offer benefits to the system as a whole.
Nevertheless, present regulatory conditions in the different
countries analysed offer barriers to the creation of these virtual
power plants.
The main barrier for Spain is the lack of flexible CHP, but, under
certain circumstances, flexible CHP proves to be more
economically feasible than traditional CHP, so it should be
considered when installing a new CHP plant. |

| The DESIRE project |
| Author: Henrik Lund |
| Abstract:
Today big power plants are used to balance most aspects of
electricity supply and demand. The DESIRE project will
disseminate cutting edge software tools and systems that will
enable small and medium sized CHP-plants to combine or 'coproduce'
their electricity allowing them to partly balance the
fluctuating output of wind turbines thus ensuring that most wind
power can be used locally, thereby relieving the pressure on
system operators to offload surplus wind. In turn this will relieve
pressure on international inter-connectors and allow international
trade in electricity to be come more competitive. This will allow
consumer electricity prices to be lower and the quality of
electricity supplied to become higher. CHP can work with wind
power to produce a balanced, more predictable, supply of
electricity because of techniques disseminated in this project. CHP
plant need accumulators (heat storage) to act in this way. When
there is excessive wind power production, the CHP unit decreases
production and relies on its heat store in the accumulator to satisfy
its heat demand. When wind production is low, the CHP plant
operates in order to build up heat stores and make up for a lack of
wind power electricity production. This is the theory of the coproduction
system being demonstrated in this project. The
techniques of coordinating CHP and wind power plant mean that
these plants can help maintain reliability for electricity supplies
rather than make a problem for the electricity system that can
jeopardise international trade in electricity. |

| The Benefit of integrated Energy and Transportation CO2
Emission Control Strategies. |
| Author: Ebbe Münster |
| Abstract:
This paper analyses mutual benefits of integrating future
energy and transport CO2 emissions control strategies. The paper
illustrates and quantifies for the case of Denmark the mutual
benefit of integrating the transport and the energy sector. In short,
the energy sector can help the transport sector in replacing oil by
renewable energy and CHP. While the transport sector can help
the energy system in integrating a higher degree of intermittent
energy and CHP.
Two scenarios for partial conversion of the transport fleet have
been considered. One is battery cars combined with hydrogen fuel
cell cars and the other is the use of biofuel (ethanol) and synthetic
fuel (methanol) for internal combustion cars. Both scenarios have
a substantial effect on decreasing the excess electricity production
caused by an eventual increase in the fraction of electricity
delivered by fluctuating sources like wind turbines.

| Wind-CHP "Virtual Power Plants" in different European countries |
| Author: Carlos Madina |
| Abstract:
The presentation compared the possibilities that regulatory
frameworks in the countries participating in DESIRE offer for the
balancing techniques proposed in the project. Europe is
facing/will face important energy challenges, so wind power and
CHP can be good solutions, but they both have problems, so the
combined use of them can reduce each technology's problems,
but, before implementing the combined use, the regulatory
conditions must be determined and, therefore, a summary of WP3
was made. As a result of the analysis, it could be seen that
conditions are good in Denmark; they can quite easily be good
also in Germany if market integration of RES is promoted; Spain
required the promotion of flexible CHP; the UK needs the
promotion of flexible CHP and a better promotion of wind power;
Poland has a good potential, but requires that the regulation takes
the right direction to promote wind power and flexible CHP, and
to effectively open the electricity market; and Estonia needs to
open its electricity market, before thinking of using these
techniques. |
