For this reason, the operation of a single-phase photovoltaic generator with battery is analyzed and the control actions required for an efficient management are proposed.

The hourly nodal market prices at the buses ends of the tie-lines are used to value power exchanges (exports or imports). These prices (or marginal costs) are parameters for the optimization procedure and their estimation is based on the mid-term operational planning published by the national system operator.The model considers cascaded hydro systems with head-sensitive plants and a DC power flow to represents the transmission network and its constraints. Optimal hourly scheduling of each plant is obtained within a medium-short term horizon ranging from one day up to eight weeks.The model is applied to the interconnected system of the San Juan province, Argentina, including the cascade hydroelectric exploitation on San Juan river composed by three reservoirs and four hydroelectric plants. The results show the optimal scheduling to maximize the revenues of the generation company that operates hydroelectric plants. The impact of non-linear production functions of hydroelectric power plants on the results are analyzed by comparison with a simplified linear modeling.","PeriodicalId":448644,"journal":{"name":"2020 IEEE PES Transmission & Distribution Conference and Exhibition - Latin America (T&D LA)","volume":"02 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131050224","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}

We use a distributed scheme with the main objective of preserving the integrity of the private information of the active agents and scalability issue. The sparsity solution is identified using the alternating direction method of multipliers. The model proposed alternates between promoting sparsity of the charging profile accomplishing EV’s constraints and minimizing energy cost.

The data obtained from the park has been statistically analysed, to assess the wind turbines’ power curves and their similarity to those given by the manufacturer. In addition, the behaviour of the wind, the active power and energy delivered by the park and by each wind turbine are studied in this investigation; their interactions and behaviour in different seasons is analysed.
