Consequently, this system will be characterised by significantly increased uncertainties on generation side and therefore, its behavior in time will be more difficult to control. This paper discusses the current methods for balance management. Furthermore it considers the limitations and presents a novel approach for balance management in a future situation.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"32 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":"132749167","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}

{"title":"Integrated Pool/Bilateral/Reserve market operation under pay-as-bid pricing","authors":"F. Stacke, P. Cuervo","doi":"10.1109/EEM.2008.4579015","DOIUrl":"https://doi.org/10.1109/EEM.2008.4579015","url":null,"abstract":"This paper analyzes the characteristics of a pricing model designed for working under the classical marginal price (MP) and the pay as bid (PAB) strategies in a combined market structure involving the presence of long term forward physical bilateral contracts (not financial contracts), and short term trades like pool and ancillary reserve services. The model allows studying the implications on the operation and the resulting economic indexes such as revenues and payments portfolios and prices. The purpose of the model is exploiting the advantages of centralized market coordination and the potential benefits of using the PAB pricing strategy like obtaining less risk in supplying loads, price stability and financial adequacy (i.e. reconciliation between revenues and payments). Because of its characteristics, this strategy is currently considered as an alternative in some actual systems. It is not the focus here to discuss which of the pricing approaches should be followed but instead ob-serving their behavior in the combined market. Numerical cases show that even considering reserve service bids independent of the generators energy bids in a joint market, the resulting reserve prices depend on the committed capacity allocated to supply the long term bilateral contracts and pool demand. This interaction reflects economic signals for both energy and reserve markets allowing generators to be able to estimate their opportunity cost in a consistent way because of the stability of prices and adequacy obtained in the three markets by using PAB. The more stable and adequate behavior (if compared with the nodal prices under marginal pricing) is verified by observing different firm bilateral contract distributions and represents an advantage for market purposes. Moreover, the pricing model allows obtaining the reconciliation of revenue and payment portfolios in all operation conditions.The proposed model has the following characteristics: i) incorporation of bilateral, pool, and reserve markets in a joint market of services; ii) the combined market allows assessing the impact of electricity products interactions on the operation and consequently on prices; Hi) Allows to compare the pay-as-bid pricing and marginal pricing approaches in several scenarios; iv) Market agents can obtain detailed portfolios in terms of revenues and payments for awarded bids; v) ensures the reconciliation between payments and revenues with a reasonable price stability; vi) Allows to obtain economic signals for estimating opportunity costs of electricity products; vii) Allows the possibility of testing several operating scenarios with price strategies in order to evaluate the impact on agents portfolios. These characteristics of the model make it attractive for planning the impact of several operation scenarios and bid strategies on the agents portfolios based on historic data.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"31 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":"125746629","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 methodology is motivated by the observations made by some authors regarding the tendency of production cost models to systematically underestimate spot prices during peak hours and to overestimate them during off-peak hours This behaviour has been attributed to the fact that traditional methodologies applied to determine the short-run marginal cost in mixed integral linear programming models, fail to consider the start-up costs into the system marginal cost. The developed methodology was applied to for the modelling of the power systems of three important European electricity markets. The results show improvements in the accuracy of the model when estimating average marginal costs and comparing them with the spot prices of the corresponding electricity markets.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"11 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":"127064570","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}

Environmental pollution renders the need for covering energy demands by renewable sources more imperative than ever. The aim of the paper is to use the estimated power production of PV units in order to evaluate the potential improvement of loss of load probability (LOLP) and loss of energy probability (LOEP). This analysis is implemented for the Interconnected Greek Transmission System (IGTS). The power output of PV units in Greece is calculated and the expected reduction of the above indices is demonstrated. Furthermore, peak shaving for the IGTS by the use of PV units is also illustrated. Finally, reliability improvement is expressed in terms of profit by comparing the cost for every kWh produced by PV units to the corresponding cost for every kWh produced by expensive units, which would otherwise cover a proportion of peak load demand.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"1 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":"131316397","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 measurement and the understanding of market power practices in the Iberian electricity market turn out to be very interesting considering the particular case of Portuguese and Spanish markets, where two antagonistic factors remain active: liberalization and the strong, direct government intervention. For various reasons, among which the difficulty in obtaining the data stands out, market power in the Iberian electricity market has rarely been measured. This work aims to contribute to a better knowledge of the way the market power occurs in the Iberian electricity market, applying a particular methodology to determine the market power, highlighted by the works of Frank Wolak in the electricity sector. Our work analyzes the results obtained in the light of the evolution of the electricity sector during the analyzed period.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"15 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":"126456517","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}

His duty is to estimate beforehand how much energy will be injected in or withdrawn from the network. Therefore, an efficient and appropriate designed market is a necessary component in order to assist the balancing management. In awareness of this, the following study examines the effects of the auction redesign on observable demand charges. We analyze the consequences caused by the launch of the common IT platform on power balance charges, particularly with regard to expected values and volatility. This allows further conclusions about possible difficulties resulting from the new market design and which may contradict the assistance for managing the grid balance. Furthermore, we compare the efficiency of the German power reserve market before and after the change of the market design by using a number of econometric approaches for analyzing structural changes. With the view to assist the establishment of a secure German energy network, we finally draw economic conclusions.","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":"125727106","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}

One way to improve the power quality is to analyze efficiently and to deeply understand these signals. The most typical disturbances in power quality have been generated in order to analyze by time-frequency transforms: wavelet transforms (WT) and S-transform (ST). Thus can be obtained a comparison of results of these time-frequency transforms. The voltage signals with different disturbances are simulated by Matlab code with 128 samples per cycle. The disturbances used in this work are carried out from standards, as voltage sag, voltage swell, short interruptions and harmonic distortion, in addition to other disturbances of transitory order as spikes, notches and oscillatory transients.","PeriodicalId":118618,"journal":{"name":"2008 5th International Conference on the European Electricity Market","volume":"28 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":"121366109","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}
