Purchasing electricity in the liberalized market, trying to adhere to energy savings projects or planning new renewable energy plants are great initiatives but often with low probability of concrete realization. For this reason, the Power System Research Group of the University of Calabria has founded CRETA, a coalition of local authorities and small companies, sharing its manifold expertise in energy field. CRETA is a non-profit organization with the mission of mobilizing, educating, informing and allowing its members to change the way they use and think about energy. CRETA works together and for its members, carrying on many projects, some concerning energy purchase in the liberalized market, energy savings in road lighting and renewable plants planning. In the paper, final results and business plans of the main CRETA activities are made available.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"26 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":"125132567","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 influence of reactive power requirements on the network voltage levels, based in the comparison of software simulation results with real-life behavior, are also studied. This paper equally analyzes the impact of DG on the substation transformers taps changers, with and without DG. Finally, it's analyzed the impact of DG on protection systems functioning in a 60 kV network.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"39 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":"125448579","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 proposed controller, based on sliding mode control technique, guarantees fast response times, precise control actions and an almost completely decoupled active and reactive power control. To reduce energy storage equipment, with consequent reduction of power losses and lifetime increase of UPFC systems, AC-AC converters with minimum storage requirements are used. These converters, usually known as Sparse Matrix Converters, are based on Matrix Converter technology and guarantee AC/DC and DC/AC conversion without the intermediate bank of capacitors, present in most AC/DC - DC/AC converters association. UPFC model is presented, using Sparse Matrix Converters, and the system controllers are designed to allow both a good steady-state and dynamic response.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"14 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":"123938239","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 method introduces two new constraints called rate of change of frequency (ROCOF) and minimum frequency as the main constraints in economic dispatch in this paper. This approach reduces emission and fuel costs of the power plants as well as transmission line losses. Therefore, this method has also the capability to control frequency in a desirable range. Finally, the proposed method is simulated on a test system. In the simulation, the economic load flow with is solved with spinning reserve, transmission lines loses and generation constraints as well as the two new mentioned constraints, i.e. ROCOF and minimum frequency constraints.

It is based on the principle of Equivalent Bilateral Exchanges - EBE which incorporates the concept of ldquopay-as-usedrdquo into the process, allowing to identify the costs to be imputed to each agent taking into account its physical position in the network and its individual use of the transmission lines. It is applied to two congestion management costs: ldquocongestion upliftrdquo and ldquorevenue inadequacy from point-to-point Financial Transmission Rights and Flow Gate Rights marketsrdquo. The EBE method is compared with the usual Pro - Rata calculation and also the Proportional Sharing Principle for the allocation of the two congestion management additional charges. The analyses are based on simulations using 3, 5 and 30 bus example systems. The results demonstrate that the proposed strategy is consistent and mitigates the cross subsidies inherent in other methods.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"37 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":"129778007","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 CO2- and electricity prices as well as the design of the allocation rules get more and more important for investment strategies of energy utilities. For this reason it is necessary to analyse the impacts of the Emission Trading Scheme on the future of power generation and investment decisions in power industry. For this purpose this paper shows some possibilities to analyse the impact of different allocation methods by using optimizing energy system models. Results show that the emission allocation scheme has a significant influence on power generation planning and power plant investments and with this on the evolution of CO2-emission and electricity market.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"23 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":"126251580","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, it has been estimated that still about 70 per cent of household customers buy electricity from their local incumbent supplier. The Finnish customers have been less active than their Norwegian and Swedish counterparts, although the retail markets were opened approximately at the same time in these three countries. In each country, there still exists several barriers to competition. One of the most significant ones is the lack of customer activity. At present, the Nordic energy regulators are making efforts towards an integrated Nordic retail market in order to increase competition. The increased amount of suppliers alone will hardly be enough to increase competition. The main focus should be in improving customer activity.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"40 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":"121027532","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 global warming is of main concern in the world. The power industry wants to make generation planning more flexible through the emission trading system. In this paper, an ANN-based method is proposed to predict one-step-ahead carbon pricing. As ANN, the radial base function network (RBFN) is used to approximate the nonlinear function of time-series carbon pricing. To improve the performance of RBFN, this paper makes use of preconditioned RBFN in a way that DA (deterministic annealing) clustering classifies learning data into some clusters and RBFN is constructed at each cluster. In addition, DA clustering is used to determine the center vectors of the Gaussian function in RBFN. Also, the Monte Carlo simulation is applied to the risk assessment of carbon pricing with the RBFN model. The risk of one-step-ahead carbon pricing is evaluated in probability. The proposed method is successfully applied to real data of the carbon pricing market.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"16 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":"123731045","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}
