Siting and installation of PV systems is performed according to a recent Greek law and by considering environmental and geographical constraints. Meteorological data about solar radiation and temperature are computed, formulated and imported to appropriate software in order to simulate the PV units and generate their power output. The above estimated power production is compared to data concerning load shedding. Assuming that a specific proportion of the eventually unsupplied power could be provided by the accessed power generation of the PV units, the reliability of the distribution system is improved. This improvement is quantified using the distribution system reliability indices SAIDI, SAIFI and CAIDI. The resulting improvement is finally expressed in financial terms through the reduction of interruption costs.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132936638","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}

Depending on the conditions of the network voltage sags propagate differently and affect different areas of the network. The analysis has been carried out to assess the influence of network topology on voltage sag propagation. The purpose of this paper is to analyze the influence of all types of connections transformers on the propagation of voltage sags on electrical system. The study shows that some transformer winding connections like Yd have more significant influence than any other type of winding connection. For analyzes the phenomenon, it was modeled on the ATP - alternative transient program - a standard IEEE 14-bus system and a sags generator, which is able to generate any kind of voltage sag with any variations of the magnitude and phase angle. With mathematical formulations based on balanced and unbalanced circuits theories.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128590245","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}

However, common drawback with solar and wind energy is their unpredictable nature. The development of supervisory systems that control and monitor the energy production from renewable sources and the evaluation of the consumption from the users is of main importance to balance production and consumption needs. The developed strategy is composed by a network of Programmable Logic Controllers (PLC) controlling locally each power plant. These local controllers are connected through a Master-Slave network, making accessible the operational data from each remote production plant. Above the operational network, a SCADA system (Supervisory Control And Data Acquisition) is installed to allow a user-friendly decentralized global management. The developed monitoring and control strategy is simulated, based on the requirements of the new renewable energy experimental park (PETER) that is being implemented at University of Evora - Portugal.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116339749","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}

Besides econometric methods, algorithms originally developed for network planning may be used for calculating optimal cost-efficient networks as a benchmark for existing networks. In this contribution, alternative approaches for calculating efficiency values are discussed and applied to two near to practice 110 kV networks. As a reference, the potential for reducing network costs over several decades is evaluated for both networks by means of a newly developed network optimization method as well. Based on these results, the loss of accuracy resulting from the exclusive use of econometric methods and highly aggregated data for benchmarking of network system operators is discussed.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117061539","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}

We define volatility as the variance of the percentage change in spot power prices over a given time interval. As shown in Sapio (2008), volatility is related to stochastic fluctuations in preference and technology fundamentals, and is tuned by the price-elasticity of demand and supply, evaluated at equilibrium. We study two cases. First, we analyze the volatility implications of a model wherein the amount of forward trading is fixed, and producers compete a la Cournot. Fixed forward trading increases spot volatility, because forwards lower the spot price level, corresponding to a less elastic region of a linear demand function. However, if the amount of forward trading is endogenous, as in the two-stage model of Allaz (1992), producers can anticipate the spot market impact of stochastic shocks on fundamentals and ldquosterilizerdquo them. As a result, spot price volatility is closer to the value implied by an efficient market. Our theoretical results are illustrated by means of a simple simulation study.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117149013","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}
