Abstract

This paper presents a novel application of General Algebraic Modeling System (GAMS) and MATLAB interfacing for optimal placement and size of distribution generation (DG) with battery. In this paper, the main contribution is: (i) optimal position of DG based on combined power loss sensitivity (CPLS) method, (ii) optimal placement of battery energy storage using combined dispatch strategy, (iii) optimal size of DG and battery have been carried out in such a way to minimize the total power loss without violating the constraints, (iv) there are two types of DGs that have been considered. The impact of DG with and without battery placement on total power loss and voltage improvement have been carried out. Voltage profile, real and reactive power flow pattern, total power loss, fuel cost, total cost, state of charge (SOC) status of battery, and power obtained by DG with the battery have been determined. The result shows the importance of DG with battery size and location. The results are obtained on IEEE-33 bus radial distribution test system and compare with another existing method also.
