Abstract
In this paper, three sources are considered, they are solar photovoltaic system, battery and grid. The main objective of this paper is i) to control the true and phantom power of the load and ii) bidirectional power flow in the grid. RL load is considered for discussion. Three-phase AC source is viewed as a grid. Solar system, load, and the battery are associated to the system through a customary bus, which acts as a point of common coupling (PCC). The proposed system is made to operate in seven different modes of operation. In all the ways of operation, the true and phantom power to the load is maintained constant irrespective of the modes of operation. The power flow to the grid is bidirectional, i.e., if procreation is excess than the capacity supplication, the surfeit potential is given to the network and vice-versa. The simulated results prove that the load power is maintained constant thereby the voltage of all the three sources are maintained within the specified limits. The tabulated results prove that the entire system voltage is within its specified limit. The entire set-up is simulated using the PSCAD software. © 2020 IEEE.
