ENERGY MANAGEMENT ALGORITHM FOR END INSTALLATIONS WITH RENEWABLE PRODUCTION AND STORAGE

This paper presents an algorithm to manage different renewable energy sources with storage. The objective of this algorithm is to regulate and control the output currents of the DC-DC converters, which are directly connected to both the DC bus and the inverter. Here, the inverter allows exchanging the energy between the DC bus and the AC grid. The implementation of the proposed algorithm to end facilities in a liberalized market is also presented and tested. In addition, the benefits of such implementation, using eight dispatches, to the operators of the grid is demonstrated. The algorithm considers several situations of the consumption, energy production, various storage capacities, grid manager's demands, forecasts of production and consumption loads. The results, which are obtained by the proposed algorithm, show a good regulation and control of the currents of the DC-DC converters, therefore a better energy management is achieved being this supported by an extensive theoretical analysis.
