We developed a stochastic optimization model whose objective function considers the financial risk and return, weighted by the risk aversion profile of the decision-maker. The financial risk is measured by the Conditional Value-at-Risk metric. The agent risk aversion profile brings important implications for resource allocation strategy definition. We apply the model in a case study considering sixteen locations in Brazil, where optimal portfolios compositions are analyzed under risk aversion levels, from the perspective of a risk-neutral agent (decision based only on the Expected Revenue) up to risk-averse (decision based only on CVaR), considering intermediate levels of these extremes. The results showed relevant changes in the portfolio allocation under different risk aversion levels. The model application contributes to discussions on this relevant subject and for mapping potential strategic association between wind power plants in Brazil. The model can be effortlessly adapted for applications in any location worldwide.","PeriodicalId":302157,"journal":{"name":"2020 International Conference on Smart Energy Systems and Technologies (SEST)","volume":"75 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116289038","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}

Due to technological advancement, government policies and the focus on reducing greenhouse gas emission, the growth can be expected to continue. Home charging of EVs will often be sufficient for short-distance travel and daily routines. However, EVs still have a limited range. Thus, for long-distance travel, a network of fast charging stations (FCS) is needed. The stochastic nature, high power demand and short duration of EV fast charging, make it in many cases a grid capacity issue rather than an energy issue. Therefore, knowledge about the load profile of FCSs is important. In this paper, a model is developed for the simulation of the aggregated load profile of an FCS. The FCS load model includes a mobility model based on actual traffic flow, EV charging curves and temperature-dependent EV efficiency. Simulations are performed using the Monte Carlo simulation technique, to get a daily load profile for the FCS. Real-world data for the studied FCS in Norway is compared with the results from the simulation to analyze the performance of the FCS load model. The developed load profile for the FCS has a high peak-to-average power ratio, which indicates that the socioeconomic profitability of fast charging stations still is low.","PeriodicalId":302157,"journal":{"name":"2020 International Conference on Smart Energy Systems and Technologies (SEST)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125309687","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}

Furthermore, to enhance the participation of the consumers in the DR programs, the Independent System Operators (ISOs) have introduced a new entity, i.e. Demand Response Aggregator (DRA). The main contribution of this paper is to investigate a novel framework to increase the profits of the DRA participating in the day-ahead electricity market, i.e. employment of an axillary generation system in the DRA entity. It is supposed that the DRA in this paper has an axillary generation system and it would lead to an increase in the profit of the DRA through avoiding the economic loss in the process of trading DR obtained by the active participation of prosumers in the electricity market. The fuel cell is introduced as the axillary generation unit to the DRA unit. In the framework proposed in this paper, the DR is acquired from end-users during peak periods and will be offered to the day-ahead electricity market. The power flow during the off-peak hours is in another direction, i.e. from the grid to the consumers. In this model, the information-gap decision theory (IGDT) is chosen as the risk measure. The uncertain parameter is the day-ahead electricity market price. The optimization problem’s objective is to maximize the profit of the DRA. The behavior of the risk-seeker decision-maker is analyzed and investigated. The feasibility of the program is demonstrated by applying it to realistic data.","PeriodicalId":302157,"journal":{"name":"2020 International Conference on Smart Energy Systems and Technologies (SEST)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122718495","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}

Therefore, innovative control schemes should be provided in the future power systems to maintain the voltage in an acceptable level. Moreover, the reactive power supply is planned to be shifted from large controlled bulk power plants to other reactive power sources. To this end, a use case is developed under the framework of INTERPLAN project – Integrated operation planning tool towards the Pan-European network. The use case aims to present suitable control functions in order to improve coordination among transmission system operator (TSO) and distribution system operator (DSO) in a way that voltage can be kept in relevant bandwidth. This use case has three main steps including reactive power flexibility assessment, TSO optimal power flow and DSO optimal power flow. This procedure aims to find the optimum reactive power set points for renewable energy resources while the reactive power capability from DSO is communicated to TSO. According to the results the information exchange among DSO and TSO are minimized by trying to set the reactive power set points of connection points constant while meeting an acceptable voltage range.","PeriodicalId":302157,"journal":{"name":"2020 International Conference on Smart Energy Systems and Technologies (SEST)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126539682","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 impact of micro grid concepts is expanding through the increase of renewable generation systems market share and the growing limitations of the power system by higher adoption of electric vehicles. A significant challenge with regards to micro grids is the development and implementation of control algorithms to ensure efficient and reliable operation. This paper presents and investigates operational strategies, namely electric vehicle load management and self-consumption, of micro grids for real-world site applications on the European Energy Forum (EUREF) Campus in Berlin, Germany. These strategies meet requirements for economical and research operation, based on the current legal conditions for renewable energy resources in Germany. A rule-based control algorithm for self-consumption of local charging stations for electric vehicles is developed and implemented in a supervisory control and data acquisition (SCADA) environment. Measurements are performed with high resolution and analyzes carried out for the collected data sets of the years 2017-2019. A discussion shows the potential of the proposed control algorithm with regards to self-consumption. The influence of operating characteristics and restrictions in real-world applications are investigated and compared to ideal operating conditions.","PeriodicalId":302157,"journal":{"name":"2020 International Conference on Smart Energy Systems and Technologies (SEST)","volume":"199 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133825357","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, we can expect more car sharing schemes using electric vehicles (EVs) to emerge in coming years. Numerous studies looked into the grid impact of EV charging and its potential to provide ancillary services, but these studies only considered regular EVs. This study compares the charging patterns of regular and shared EVs and creates insight in the grid impact and potential to provide ancillary services with future adoption of shared EVs. Four scenarios for the adoption of shared EVs are proposed, and a method to generate a set of future charging transactions based on historical charging data is presented. The analysis is performed using charging data from an EV sharing company in the Netherlands. Results indicate that charging demand peaks and grid congestion levels decrease substantially with higher adoption of shared EVs. Adoption of shared EVs increases the potential of EVs to provide ancillary services, due to a higher charging flexibility of shared EVs.","PeriodicalId":302157,"journal":{"name":"2020 International Conference on Smart Energy Systems and Technologies (SEST)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132593374","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}
