N2 - In this work, the behavior of the electrical network with the insertion of energy storage and solar generator is analyzed. Steady-State simulations are performed in Matlab using the power summation method. The consumption profile is defined as the average hourly use of the appliances in a typical residence, and the generation profile is defined using the solar irradiation data collected at the Tanquinho solar photovoltaic plant in Campinas, Brazil. The simulated method is validated with analytical calculation and is used to calculate the modules and angles of the voltages in the buses. Six buses of a power distribution system (DS) based on the IEEE standard of 30 buses are used. The results obtained are analyzed according to the Brazilian standards that determine the voltage ranges in the DS. Bus 5 does not meet the recommendations of the standard (voltage less than 0.92 p.u.), usually at power consumption peaks that occur between 7 pm and 9 pm with a voltage of 0.8084 p.u. and stabilizes in the appropriate range with the inclusion of the storage, alleviating the load demand. The solar generator system has its highest production around 12 pm (maximum of 1.05 p.u.) that can be stored if it exceeds the voltage limits. In this way, the use of storehouses in conjunction with solar generator system can be used (in some cases) in a way that is designed to solve voltage problems.
