Design of PV system peak power adjustment based on measured data

The maximum power production limit is assigned to licensed clients with photovoltaic (PV) system. For safety reasons this limit is mainly determined to be equal to the PV system power output limit. The limit does not have to be the same as installed PV system power. Maximum power of electric energy delivered to distribution network will depend on client’s consumption behavior, as PV system production will primarily supply client’s consumption. Only surplus of produced energy will be delivered to distribution network. If one can learn client’s behavior and combine it with PV system production data, it is possible to manipulate PV system power. If so, the client will be able to produce more energy daily than it was supposed to, but also will not increase the assigned maximum power limit. In this research a single instance of calculation for PV system power increase is provided using measured data of PV system production and energy counter on distribution network. Main goal is to get as much energy possible from client but keep everything from escalating regarding contract with electrical energy distributer and supplier. Obviously, the worst-case scenario would be on a day with the highest energy production while maintaining average consumption characteristics.
