Simulation and Monitoring of Energy Flows in a Micro-Grid

This paper will present a possible example of the operation of a micro-grid in which there are several sources of distributed generation and electricity storage structures in the form of Electric Vehicle Batteries (BEV) and the Battery Energy Storage System (BESS). The starting point of the simulation is the energy balance formed between the difference of the power generated from the renewable energy sources and the entire consumption of the micro-grid. The simulation proposes the implementation of a mathematical algorithm that will realize the entire energy management system of the micro-grid in order to manage in an efficient and intelligent way the available resources. Topical notions such as the charging / discharging flows of BESS will be treated, respectively the energy buffer that Electric Vehicle (EV) can offer through the discharge flow Vehicle to Grid (V2G).
