Two papers at the IEEE International Conference on Environment and Electrical Engineering
The paper entitled “Performance analysis of EV stations optimal operation in DC microgrid configurations” and the paper entitled “Multistage day-ahead scheduling of the distributed energy sources in a local energy community” have been published in the proceedings of the 2020 IEEE International Conference on Environment and Electrical Engineering and 2020 IEEE Industrial and Commercial Power Systems Europe!
In the first paper performances of different DC microgrid configurations with electric vehicle stations are evaluated, by solving alternative optimal operation procedures, aiming at minimum operation cost and minimum power exchange on daily horizon, and deriving proper technical and economic indicators. The methodology is applied to a realistic DC microgrid installation.
The second paper presents a multistage approach for the day-ahead scheduling of a local energy community (LEC) aimed at considering the uncertainty associated to both the generation from renewable sources and the energy consumption. The considered LEC corresponds to a community of prosumers connected to the same distribution power network. In general, the considered prosumers are equipped with photovoltaic generating units, energy storage units, and local loads. The scheduling of the LEC is defined by a distributed optimization procedure based on the alternating direction method of multipliers (ADMM), which minimizes the total energy procurement costs. The adopted approach adjusts the operational planning according to the current operative conditions by means of a scenario-based multistage procedure. This paper describes the scenario tree generation and an intraday decision-making procedure based on the day-ahead solution. Moreover, numerical tests are presented for several operating scenarios.
