abstract

• The use of electric distributed power generation with renewable energy sources, has been increasing due to their advantages compared to the conventional fuel-based sources. An appropriate control strategy allows voltage and frequency regulation, supplying power directly to the near connected loads, improving power quality characteristics. In this sense it is possible to use optimization techniques to minimize the cost of the power generated, and supply the full power demanded by the load. In this work one optimization criteria is applied in a microgrid, achieving simulation results that takes into account the whole dynamics in a radial connected system, using power electronics converters detailed models and all control levels in the hierarchical control strategy. Hence the power generated by grid-feeding converters is optimal to reduce the operating cost of the microgrid, taking advantage of the reactive power regulation capability provided by the controllers to improve the system performance parameters and the efficiency. © 2021 IEEE.
