These designs are analyzed comparing public data and actual practices in use among different TSOs in comparable interconnected zones in Europe end the US, concluding that the zonal design is better suited for the European context. Concerning the Day-ahead signal, in a zonal design, market coupling (eventually with flow-based) allows an optimized use of interconnection capacity between control areas and the use of specific operating practices inside each control area. In nodal designs, control areas match market zones, but very poor results are observed at their interconnection, with inconsistency between price differentials and flows. Furthermore, the nodal design has some drawbacks concerning the optimization of maintenance periods and the leveling of operating procedures. A comparison of Day-ahead congestion revenues in the chosen areas shows that revenues were much greater in the US (1 798 M$ vs. 255 M€ in 2010). These values may reveal the different degree of development of the grid and may justify the choice of a nodal approach in the US. Inside a control area the Real-time signal is always nodal when needed, even in zonal designs; among different control areas the nature of the signal depends on the coordination level among TSOs. Topological remedial actions at almost no-cost seem easier to perform in a zonal design.","PeriodicalId":383754,"journal":{"name":"2012 9th International Conference on the European Energy Market","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124488030","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 increasing importance of energy markets together with the foreseen reduction in incentive schemes for renewable energy require to extend the classic maintenance decision process and to consider also market and weather information. In this paper, we propose a model that extend classical maintenance scheduling so to include forecasted market prices and weather conditions. The theoretical and computational aspects employed for the design of the market-based maintenance strategies able to maximize profits are considered. The proposed maintenance schedule optimizes a discounted cumulative profit of a wind generation portfolio in a fixed-time horizon (e.g. two years ahead) subject to the technologically-derived maintenance time constraints. Furthermore, logistics costs are also considered so to evaluate impacts of the location of warehouses. Results point out that taking into account market and weather opportunities in the design of the maintenance strategy allows one to achieve a more complete scheduling for a given set of wind power plants.","PeriodicalId":383754,"journal":{"name":"2012 9th International Conference on the European Energy Market","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115591686","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}

This paper focusses on the technical feasibility of the German nuclear phase-out on the short term (2012-2022) and on a European scale. A detailed electricity generation simulation model is employed to address the issues at hand, including the German transmission grid and its international connections. Power plants are modelled with a high level of technical detail. A range of different renewable energy sources (RES) scenarios is considered. Results are presented for the change in generation mix, on the flows in the electric network and on operational reliability issues. The simulations show that the nuclear generation will be replaced mainly by coal and lignite based generation. Furthermore, the results indicate that export in 2012 on high demand - low and medium RES infeed days will be problematic. Keeping the seven oldest nuclear power plants (NPPs) online, would mitigate this for days with medium RES infeed. If the capacity that is currently licensed is built before 2017, the situation improves. However, the situation on the northern part of the transmission grid stays critical. In 2022, the assumed extension of the generation capacity will not suffice. Keeping the NPPs due to shut down after 2017 on line would mitigate these contingencies.","PeriodicalId":383754,"journal":{"name":"2012 9th International Conference on the European Energy Market","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117340276","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}

This applies not only to producers using renewable energy sources and cogeneration under feed-in tariffs, but also to all conventional power plants that undersigned a power purchase agreement in the 1990s. Because no comprehensive public information about State guaranteed prices is available, research was first carried out to unveil generation legacy contracts' volumes and then costs and their impact on consumers. A producers' database was created by the authors which enables an accurate assessment of the volumes of electricity with and without State guaranteed prices. In a previous paper the authors have validated the data set and the volume computation methodology for the period 2000-2010 and provided an estimate of those volumes in the period 2011-2030. This paper estimates average prices per producer type and assesses generation legacy contract costs in the period 2011-2030. Moreover, the paper computes the impact of generation legacy costs upon end-user average electricity prices and generation costs for several scenarios of market prices and demand.","PeriodicalId":383754,"journal":{"name":"2012 9th International Conference on the European Energy Market","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115690172","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}

A recent study assessed optimal locations for wind power plants based on the calculation of production costs derived from wind speeds modeled in a spatially explicit way for Austria. However, wind power production, as any other intermittent renewable power source, can be highly variable due the stochastic nature of wind. This may incur additional costs for regulating power or storage devices. Selecting wind power production sites by minimizing the variability of joint power output may be one way to manage intermittency. We have generated synthetic time series of wind power production using data from a wind atlas and meteorological stations. We used the time series in an optimization model to analyze how variability in the output of newly added wind turbines can be decreased by diversifying the sites of wind farms. Results indicate that hourly variability as well as seasonal variability can be reduced by diversification of turbine sites, however, there is a trade-off. Model results indicate that diversification will reduce rents of wind turbine developers by increasing costs although all assessed sites are profitable when considering current feed-in tariffs. This implies that regulators could increase the usability of wind power plants by taking into account diversification of locations without increasing costs for consumers.1","PeriodicalId":383754,"journal":{"name":"2012 9th International Conference on the European Energy Market","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115111487","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}
