Being an important link between wholesale and retail electricity markets, these DISCOMs are exposed to risks on both sides. Under such circumstances, they are looking for new analytics to optimize operations and maximize profits. Load forecasting is one such predictive analytics used by DISCOMs to minimize risks. With increasing level of penetration of intermittent wind and solar energy in the generation at bulk as well as distributed level, both supply and demand have become uncertain. With certain benefits and incentives offered to the customers, demand can be made flexible and controllable in nature. Such flexible demand can help in minimizing the demand supply gap. Also the response of load is faster than the conventional generation resources which have machine inertia. Flexible demand is thus one of vital feature of future grid. Demand Response (DR) can be considered as a way to utilize this flexibility of load by adjusting the consumption profile thus assisting in dealing with the increased uncertainty and improving the power system operational efficiency. With the DR programs implemented, the DISCOMs will now have to forecast not only the demand of electricity but the net demand adjusted after accommodating demand response. In this paper, we analyse the impact of DR on the net demand profile of DISCOM considering the end consumers with varying demand profiles and varying preferences. We propose a new approach to forecast demand with modelling of the DR. The proposed approach gives a Probability Density Forecast (PDF) of demand using a non-parametric approach based on Kernel Density Estimation (KDE). The proposed model will help DISCOMs for developing demand bidding strategies in a market where DR programs are being implemented.","PeriodicalId":416082,"journal":{"name":"2017 14th International Conference on the European Energy Market (EEM)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134647056","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, as both consumption behavior and consumer structure change over time, their predictive power may have deteriorated. In addition, they do not account for regional differences within Germany. Therefore, we compared their forecasting accuracy with two newly developed alternative standard load profiles, differentiating between households and commercial enterprises. We calculated the new profiles based on regional, more up-to-date aggregated consumption data and a limited set of smart meter data. Furthermore, we varied the number of seasons and day types included in the profiles. A comparison of our new load profiles with the existing Standard Load Profiles revealed significant improvements in forecasting accuracy. Improvements are mainly resulting from improved input data (regional and more recent data set), but the utilization of smart meter data as well as variations in day types and seasons also reduced forecast errors.","PeriodicalId":416082,"journal":{"name":"2017 14th International Conference on the European Energy Market (EEM)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122246594","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}

There are several electricity balancing pilot projects having already been started or will start in the near future. The work presented in this paper focuses on projects with the geographic scope of Central Europe. This includes the common activation of automatic Frequency Restoration Reserve (aFRR) in Austria and Germany as well as the common procurement of aFRR in the above-mentioned area, which is planned to start mid-2017. The start for common procurement and activation of manually activated Frequency Restoration Reserve (mFRR) has not yet been published, but will also be analysed within this work. In addition, the impact of a further extension of the common balancing area to Belgium and The Netherlands is analysed. The focus of the study is on how common procurement of aFRR and mFRR influences wholesale electricity market clearings and how it interferes each other. The quantitative results confirm that common procurement of balancing capacity (aFRR and mFRR) in the simulated region has significant advantages in terms of cost reduction, CO2 emissions and increased flexibility in the electricity system. Furthermore, the common procurement of mFRR interferes the procurement costs of aFRR in a positive way, meaning that further reductions can be achieved.","PeriodicalId":416082,"journal":{"name":"2017 14th International Conference on the European Energy Market (EEM)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124173389","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}

Hydrogen can be produced from natural gas in combination with carbon capture and storage to utilize the natural gas resources without significant CO2-emissions. The hydrogen can be liquefied and transported to regions with energy deficits. This creates a demand for hydrogen produced from electrolysis of water, which facilitates wind power development without requiring large investments in new transmission capacity. A regional optimization model is developed and used to investigate sizing of the electrolyser capacity and hydrogen storage, as well as regional effects of producing hydrogen from electrolysis. In the model, the transmission grid is represented by dc power flow equations and opportunities for wind power investments in the region are included. The model is used in a case study which shows that hydrogen storage contributes to significantly increase grid utilization, even with small amounts of storage. Increased regional transmission capacity results in more wind power development compared to increased capacity towards the central grid. Hydrogen storage is only profitable to reduce congestion in this deterministic model, thus using hydrogen storage to reduce the costs in the spot market is not profitable.","PeriodicalId":416082,"journal":{"name":"2017 14th International Conference on the European Energy Market (EEM)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130242734","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}

Since electricity demand varies as does the supply by RES, the remaining residual load must be covered by flexible technologies that are required to balance the different types of fluctuations. In this study, these flexibility options are divided into three categories: increasing the residual load, decreasing the residual load and shifting the electricity demand / supply temporally or spatially. Furthermore, typical technological options are discussed for each category, and four flexibility criteria are used to compare their technical and economic characteristics. These include the activation time, duration of flexibility provision, number of activations and activation costs. The study reveals that various options exist and no one technology dominates. However, within the flexibility categories, it can be shown that some appliances have advantages in three of the four categories compared to the other options. Ultimately, the choice of the most appropriate flexibility option depends on the requirements of the energy system. It can be concluded that a mix of technologies will be needed to cover the future flexible demand that may include short-term changes of the residual load as well as long-term downturns of RES generation.","PeriodicalId":416082,"journal":{"name":"2017 14th International Conference on the European Energy Market (EEM)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117172288","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}
