Wind power integration in a liberalised electricity market (WILMAR)

Objective

Objectives and problems to be solved:
1 To develop a planning tool to analyse the integration of renewable power technologies to be applied by system operators, power producers, potential investors in renewable technologies and energy authorities.
2. To analyse the technical impacts connected to the introduction of substantial amounts of wind power in the northern part of the European electricity system - covering the Nordic countries plus Germany.
3. To analyse the performance of different integration measures in a liberalised electricity system. Possibilities for integrating fluctuating power production by optimising the interaction of the existing units in a given electricity system, possibilities lying in power exchange between regions, and the performance of dedicated integration technologies like electricity storage will be evaluated.
4. To quantify the costs connected to the integration of large shares of wind power in a liberalised electricity system.
Description of work:
A fast introduction of large amounts of intermitting renewable power production as wind power can cause technical and economic problems of the power systems due to unpredictability of wind power or due to unbalance between local power demand and intermitting power produced causing grid instabilities. In the northern part of Europe, systems operators are already facing grid-instability problems in periods with heavy wind. This project will investigate these problems and develop a modelling tool, which can be used to simulate alternative solutions providing a firm basis for decision making by actors at the power pools. The model will cover the two power pools: NordPool and European Power Exchange, i.e. Germany, Denmark, Norway, Sweden and Finland. With the starting point in existing models an hour-per-hour simulation model is developed to analyse the integration of renewable power technologies into the power system. This modelling tool is used to investigate the technical and cost issues of integrating large amounts of wind power into the electricity system.
The modelling and simulation effort consists of two parts, investigating
1. the wind integration ability of large electricity systems with substantial amounts of power trade in power pools, and
2. System stability issues, i.e. the wind integration aspects connected to fast (below one hour) fluctuations in the wind power production. The developed model will be tested by different end-users, systems operators, power producers and other actors at the power pool, which are expected to be users of the final model as well. Finally the results obtained will be summarised and used to provide recommendations about the technical integration possibilities, the integration costs of wind power and the organisation of electricity markets and power pools.
Expected results:
Development of a strategic planning tool for the integration of renewable power production. Recommendations about how the electricity and heat markets should be organised to enable exploitation of the most cost-effective mix of wind power integration possibilities in a given electricity system. Quantification of the costs connected to the integration of wind power in a liberalised electricity market. Recommendations about the usefulness and performance of different types of integration measures.
