Abstract
Photovoltaic grid-connected system of local object with a battery when using a grid inverter with an “open” input is presented. The expediency of the structure of the converter unit use equipped by controllers of a photoelectric battery and battery with independent (external) control and the possibility of charging the battery from the grid is substantiated. It expands the possibilities of energy generation and distribution control in the power supply system of a local object with several tariff zones using an intelligent energy management system in all operating modes including autonomous. The structure of the power control channel is developed, while it is possible to use a standard MPPT controller to control the generation of a photovoltaic battery. The simulation model of the system is developed. The simulation results are given. References 9, figures 4.
