For some DG technologies, like wind power and PV, another reason significantly limiting their participation in the electricity market trade is the inherent intermittency of power generation process which might result in a high risk of financial losses due to additional balancing needs. At the same time being connected together, DG and RES technologies can complement each other in balancing out the total operation result. Aggregations of distributed generators of different technological types (“DG clusters”) lead to aggregated generation profiles. These aggregations are suitable for minimizing generation prognoses errors and resulting balancing needs - experience of Denmark, Germany and UK can prove it. In this article different approaches to influence the DG clusters' properties to adjust them to market needs have been investigated and necessary recommendations for smaller size renewable energy producers for their electricity market participation have been worked out.","PeriodicalId":310310,"journal":{"name":"2010 7th International Conference on the European Energy Market","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126571465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In some countries, system operators demand wind turbines to provide some sort of ancillary services, such as reactive power control and frequency/active power control in order to increase system stability. This paper focuses on the provision of primary frequency control by wind generators and proposes a novel control strategy for active power reserve provision of doubly fed induction generator wind turbines. The proposed control strategy aims at maximizing the rotational kinetic energy, using the differential evolution. The control variables in the optimization process are the rotor speed and the pitch angle, considering the given power reserve factor. The proposed control strategy is compared to the strategies proposed by other authors. The results show that, compared to the existing methods at the same de-loaded power, the proposed method yields more rotational kinetic energy, that is released into the system in case of frequency deviations, thus increasing frequency stability of a power system.","PeriodicalId":310310,"journal":{"name":"2010 7th International Conference on the European Energy Market","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115850881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main purpose of the paper is to identify determinants of the energy market's intra-day volatility. Firstly, the investigation is a contract-by-contract, range-based volatility measure. The findings are (1) long memory in volatility the longest contracts (year), but not for the shortest (month), (2) the first difference contemporaneous and one-day lagged trading volume measures influences daily volatility positively and consistently over all contracts, (3) trading volume seems to dominate the Samuelson (maturity) and the open-interest hypotheses thus manifesting earlier findings of future markets. Secondly, the paper applies a relatively new methodology to cope with dynamic panel data models, where every contract in the market is organized as a panel. The GMM-type estimator for dynamic panel-data of Arellano [1] is therefore implemented. The results show appropriate specification residual tests and demonstrate firstly the importance of volatility serial correlation. This estimator also shows that the change in daily trading volume is the major determinant of intra-day volatility. In contrast to the segmented analyses, time to maturity shows increased intra-day volatility influence while the measures of bid-ask spread and open interest show decreased significance. The main GMM findings are therefore that the change in trading volume (including lags) and time to maturity are major determinants of intra-day volatility.","PeriodicalId":310310,"journal":{"name":"2010 7th International Conference on the European Energy Market","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132244865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Especially the share of renewable energies, such as wind and solar power, will increase rapidly in the years to come. As a result, the unit commitment of the residual power generation pool, e.g. thermal and hydro power plants, will be influenced by the volatile feed-in of renewable energies depending on the installed capacity. In addition, further consequences concerning an increase of reserve capacity can be expected. Thus, there is a motivation to investigate the impact of a significant share of renewable energies on the European power generation system. Using market simulation methods supply and demand for electrical energy can be simulated under consideration of technical constraints of power generation and transmission for a defined system. In view of these circumstances this paper presents a market simulation method and resulting future scenarios of the power generation system in detail. The approach focuses on the evaluation of the structure as well as economics, i.e. the impact on the generation pool and its marginal generation cost for electrical energy and the transnational interdependencies, in case of a significant share of renewable energies in the power generation system.","PeriodicalId":310310,"journal":{"name":"2010 7th International Conference on the European Energy Market","volume":"408 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132306086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
