An off-grid hybrid system scheduling for a remote area

Abstract

With the advent of renewable technologies in the power market, it is of keen interest of researchers to utilize these technologies in the most optimum manner. The unit cost of energy particularly from solar energy is much higher when compared with conventional energy sources. Nowadays, the emphasis is on the integrated utilization of these resources to minimize the cost and maximize the profit. In this paper, an optimal daily scheduling approach for a solar-wind-diesel system with battery storage has been presented. A mathematical model has been developed with the objective of maximizing profit. The problem has been optimized using Linear Programming technique using Primal-Dual Interior Point Method. This model is then tested on a test system and in order to obtain results MATLAB codes have been developed. © 2012 IEEE.
