In addition, the number of electric vehicles (EV s) are expected to grow rapidly in near future. Both situations increase requirements for reinforcement arrangements. Consequently, the demand for concepts and tools estimating the reinforcement dimensions and costs on regional and national level has arisen. However, challenges in terms of complexity, heterogeneity and data availability of the grid impede the design of the models. This paper presents a stochastic methodology to quantify the costs and a comparison to existing studies. Results indicate that total required lengths for distribution grid line expansion over all voltage levels of the German power grid case and their total cost deviate moderate to renowned methods for REs. Furthermore, increasing share of EV s lead to much higher grid reinforcement requirements than REs and Voltage Regulating Distribution Transformer can reduce REs grid line expansion costs dramatically.","PeriodicalId":334674,"journal":{"name":"2018 15th International Conference on the European Energy Market (EEM)","volume":"347 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115296340","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 the NES2017, electricity production from RES reaches a share, in 2030, equal to 55% of the gross domestic consumption of electricity (GDC-E). In this paper we present the impact assessment of the achievement of such target on the development and on the operation of the power system. The analysis started from an energy scenario developed with the long term energy model TIMES-Italia. Then, using sMTSIM, a simulation model of the Italian power system, the main criticalities (congestion, overgeneration, energy not supplied, etc.) have been identified and quantified. The technical and regulatory measures to mitigate the impact of such critical issues, have been evaluated on the basis of a cost/benefit analysis. Finally, the amount of investments needed and the impact on electricity cost have been estimated.","PeriodicalId":334674,"journal":{"name":"2018 15th International Conference on the European Energy Market (EEM)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116207291","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}

Most capacity market designs are focused on long term horizons. We develop an optimization-based framework for clearing the capacity market over a short-term horizon. Participation strategy for generation units with firm capacity based on long-run marginal pricing is analyzed. Based on a German case study, we compare three different market frameworks: a proposed short-term capacity clearing process, a long-term capacity clearing process, and an electricity-only market. Results show that, under perfect competition assumptions, generation units that are necessary to maintain the level of supply adequacy deemed by the TSO, are able to recover their total costs under both short-term and long-term clearing, while the energy-only approach cannot ensure long-term supply adequacy. We also show that clearing the capacity market in short term horizons will decrease the cost of ensuring adequate supply by about 28 %.","PeriodicalId":334674,"journal":{"name":"2018 15th International Conference on the European Energy Market (EEM)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124294687","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}

Consequently, in many real applications, the performance of electricity price is not appropriate. The goal of this article is to analyze the available market data and characterize circumstances that affect the evolution of prices, in order to allow the identification of states that promote price instability and to confirm that class segmentation allows increasing forecast performance. A regression technique (based on Artificial Neural Networks) was applied first to the whole set and then to each class individually.

Electricity price time series exhibit variable means, significant volatility and spikes, which places high demands on forecasting models. Moreover, in recent years researchers and practitioners have come to understand the limitations of point forecasts and require models to generate probabilistic forecasts. In contrast to point forecasts, the probabilistic forecasts takes the form of a predictive probability distribution over future quantities or events of interest. In the paper the probabilistic forecasting model based on Nadaraya- Watson estimator is proposed. The model generates the point forecasts as 24-component vectors representing day-ahead electricity prices. The probabilistic forecasts are calculated as quantiles based on the residual distribution for historical data forecasts. The performance of the proposed model is validated by testing on data from the Polish electricity market.","PeriodicalId":334674,"journal":{"name":"2018 15th International Conference on the European Energy Market (EEM)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131511399","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}

To evaluate the accuracy of a forecast, observed values must be compared against forecast values over a test period. At times, however, the actual generation of a wind farm can be affected by factors that are outside the scope of the forecast model. Evaluating a forecast using a data set that includes such out-of-scope observations might give a biased or inconsistent assessment. In the data preparation phase, then, the evaluator should identify out-of-scope data and decide whether to include or remove these from the data set. In this paper, we carry out an empirical study based on data from an existing wind farm and a number of day-ahead forecasts in order to highlight the effects of including in- and out-of-scope data on forecast accuracies. The results show that the outcome of the evaluation varies significantly depending on the criteria adopted in the data selection.","PeriodicalId":334674,"journal":{"name":"2018 15th International Conference on the European Energy Market (EEM)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131627737","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}
