Optimal calculations of electrical power flow control for grid-tied solar system by using CPLEX – Matlab connector

Abstract

In Vietnam, solar power systems are currently encouraged to develop, which helps to reduce energy consumption costs, alleviate poverty, increase the electricity supply resources for the national grid, and contribute to the protection of the environment. However, the most efficient use of solar systems is an interesting problem to many scientists. This article introduces an optimal management method for power flow control of grid connected solar power systems. The considered system includes solar cells, storage batteries, which are connected to a grid to meet the power requirements of the load. The optimal power sources-to-load distribution between the source and load allows minimizing the cost of electricity consumption in the context that the surplus power from solar cells may be sold to the grid; The 3 selling price levels of electricity taken at different time intervals of the day are applied to manufacturing industries, trading and other services..
