ГІБРИДНА ФОТОЕЛЕКТРИЧНА СИСТЕМА З АКУМУЛЯТОРНОЮ БАТАРЕЮ ДЛЯ ЛОКАЛЬНОГО ОБ’ЄКТУ З ЗАВДАННЯМ ПОТУЖНОСТІ, ЩО СПОЖИВАЄТЬСЯ З МЕРЕЖІ

Abstract

The issues of increasing the efficiency of a hybrid photovoltaic system with a storage battery used to meet the own needs of a local object are considered. This is achieved in the case of a setting according to the forecast of power consumption from the grid, which ensures the formation of the necessary graph of the degree of charge of the battery. A technique for determining the parameters is substantiated when achieving the maximum reduction in the cost of electricity consumed from the grid for the accepted load schedule for the average monthly generation of a photovoltaic battery in summer. Implementation scenarios are proposed in accordance with the accepted billing of payment for electricity. The possibility of leveling the graph of power consumed from the network and reducing consumption during peak hours is shown. The invariance of control is confirmed under the conditions of load changes over time within a certain energy value at intervals in the daytime and in the evening. The possibilities of implementing the proposed control scenarios are confirmed by modeling energy processes in the daily cycle. At the same time, archival data on the generation of a photovoltaic battery from open web resources were used. The solutions obtained are the basis for the design of software control complexes for photovoltaic systems with batteries with improved energy efficiency.
