The current state of the grid segment is shown and its inability to host higher than present amounts of DG is discussed. Consequently, technical solutions to overcome this problem without reinforcing the grid are presented. Different strategies of active voltage control are studied on the basis of extensive simulations using the DIgSILENT PowerFactoryreg software. Detailed economic analyses for different grid segments as well as producer-driven strategies (e.g. local or coordinated voltage control) for voltage control are performed. These approaches are furthermore compared to conventional grid reinforcement measures, showing that investments in new smart grid technologies may even lead to lower overall cost for society.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"10 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":"125575599","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}

At this moment, electricity market is open to eligible customers only. Eligible customers are able to choose their supplier and currently these are all non-households. Starting from July 1st, 2008 all customers, including households, will become eligible and the market will hence be fully open. Therefore, a suitable method for Croatian market simulation is needed. This paper presents possibilities of using an agent-based model to simulate the Croatian electricity market. Agent-based models represent each market participant as an independent software agent. Each agent has its own strategy and decision-making process. Agents are able to learn and adapt to their environment. EMCAS (electricity market complex adaptive system) is a computer simulation program for agent-based simulation. This paper presents an EMCAS case representing mutual influences of market participants in the emerging Croatian market.

Increasing investment requirement has been one of the drivers behind the power sector liberalization process. One of the major steps in liberalization process has been publishing of electricity market law. The law introduced unbundling of activities and establishment of the regulator and stipulates a bilateral contracts model complemented with a balancing market, a regulated third party access regime, and eligible consumers scheme. The law also introduced changes in tariff setting approach which can be summarized as cost reflectivity, avoidance of cross-subsidies and employment of regional tariffs. Implementation of the BSR introduced a balancing mechanism, with new rules defined for financial settlement of balancing activities and with significant changes to the rules for settlement of imbalances. There has been progress in design of the final market structure.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"65 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131638913","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}

EMCAS provides a framework for simulating deregulated markets with flexible regulatory structure along with bidding strategies for supply offers and demand bids. VALORAGUA provides longer-term operation plans by optimizing hydro and thermal power plant operation for the entire year. In addition, EMCAS uses the price forecasts and weekly hydro schedules from VALORAGUA to provide intra-week hydro plant optimization for hourly supply offers. The integrated model is then applied to the Iberian electricity market which includes about 111 thermal plants and 38 hydro power plants. We then analyze the impact of hydro plant supply offers on the market prices and ways to minimize the Gencospsila exposure to price risk.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"10 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":"114224036","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}

It is shown that the price components are determined by the gas production and transportation costs as well as by the marginal markups for reaching the limit values in gas production and transportation. Simultaneously, the similar price components related to gas losses are found. The technique of the nodal price calculation is illustrated by the example of the Unified gas supply system in Russia. The nodal gas price components were studied on the basis of the retrospective information on gas production and consumption in the constituent entities of the Russian Federation (RF) in 2005. The paper shows the relationship among different components of the nodal price.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"18 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":"114331933","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 this paper the study on changing risk level for Finnish distribution companies is done using case examples as well as based on theoretical discussion.

The study shows that all the actions taken into account are not sufficient to achieve the CO2 emissions target hypothesized for 2020. Only high penalties on CO2 emissions, such as the ones deriving from the application of an additional carbon tax, causing a complete switch from coal to gas (with a consequent hardly acceptable dependency on natural gas), could reduce the distance from the target to an amount that could reasonably be covered by the Kyoto protocol flexible mechanisms.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"51 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":"121322184","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}

Today it is widely recognized that, in regard to public services, the aim of regulation should be to maximize the social wealth added (EWA). This wealth includes consumers surplus (ECA), tributes paid to government (EGA) and investor value added (EVA). Thus, regulation implies both efficiency, regarding the location of resources, and fair price levels. The task is seriously impaired by informational asymmetries, and a second-best optimum is only attained with incentive-compatible contracts. Those problems, among many others, can be treated with the proposed model. In order to clarify some of the issues, an example is developed showing the social wealth added under several instances of market operation: regulates vs. unregulated firm, level of taxation, and optimized vs. non-optimized investment and resources.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"20 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":"116576337","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}
