Application of Enhanced Sine Cosine Algorithm for Optimal Allocation of PV- DG and DSTATCOM in Distribution Systems

Abstract

The allocation and optimization of renewable energy and shunt compensators remains a challenging task to enhance the performance of system efficiently. This paper suggests a new methodology to determine the optimal placement and ratings of the Photovoltaic based distributed generator (PV- DG) and Distribution Static compensator (DSTATCOM) in radial distribution systems. An Enhanced Sine cosine algorithm (ESCA) is applied to solve the allocation problem of the PV- DG and DSTATCOM. The ESCA is proposed for improvement the searching capabilities of the conventional Sine Cosine Algorithm (SCA) by using the Levy Flight Distribution (LFD) and adaptive operator. to demonstrates effectiveness of the proposed algorithm, it has been tested on IEEE 33 and IEEE 69 bus systems for loss minimization by PV-DG and the obtained results are compared with other algorithm. The ESCA is applied for optimal inclusion assigning the PV- DG and DSTATCOM for a multi-objective function which comprises of three objective functions including the power loss reduction, voltage profile improvement and voltage stability enhancement. The outcomes reveal to that optimal inclusion of the PV- DG and DSTATCOM can enhance the performance of the system considerably. In addition of that the proposed algorithm is superior for solving the allocation problem compared with the state-of-the-arts algorithms
