| Popis: | The growing search for the electrical system modernization improve the development and implementation of the microgrids concepts. Microgrids consists in a component of the distribution grid, with connected or isolated operation capabilities, and distributed energy resources within the electrical parameters' limits. Thus, this work presents an iterative optimization method to obtain the optimal sizing of a microgrid combined with a photovoltaic generation and a battery storage system. The objective of the optimization is to obtain the lowest value for the annual costs of the system (ACS), maximizing solar generation, subject to operational restrictions. After presenting the annual cost of the system, an average hourly price of the microgrid was calculated, resulting in 0,414 R$/kWh. This price is lower than average hourly price of utility tariffs. Hence, the results validated the proposed optimization method. |
