With increased interest in renewable energy sources, such as photovoltaic farms, a number of studies whose aim was the analysis of their positive and negative impact on the power system was carried out. From the point of view of the system operator, the suitable place of installation and the size of such plant in the network can have a positive impact on the value and direction of power flow, voltage levels, the value of the power loss, short- circuit currents and power factor. However, the biggest difficulty in the application of the farm is its unexpected production characteristic which depends mainly on the weather conditions changing randomly during the day. The most desirable case is a period when this farm is capable of being installed in depth of the network to reduce daily peak demand for electricity. The energy from big, centralized plants working in the system must be delivered to the customers at this time, which generates additional costs of starting units, working in short period of time and increases power losses on lines, which must send higher energy values. Accordingly, the sense of use of an external energy storage systems cooperating with photovoltaic installations is clear. For the grid operator, in the case of large PV farm desirable to be able to use the extra energy of the battery power and the ability to use the farm to reduce the afternoon and evening peaks. This may positively affect production costs and transmit additional energy to the system.
