Techno-Economic and Environmental Benefit Analysis of PV and D-FACTS Enriched Modern Electric Distribution Grid with Practical Loads

Abstract

In the current era, expansion in the power system has led to an increase in the Distributed Generation (DG) planning to accomplish the increase in demand. Hence because of the opted DG’s inappropriate planning, the system gets unbalanced with an increase in losses, voltage profile imbalance along with reliability issues. Here, the modernized IEEE 69-bus network is considered for appropriate DG’s planning. In this study, one important factor, which is the Line Fault Current Level (LFCLevel) along with Real & Reactive Losses (R Loss & Q Loss), Voltage Deviation Profile (V DP), and Network Reliability (R N ), is considered as an index in the objective function, which makes the proposed Multi-Objective Function (MOF) a novel MOF (nMOF). The cost-economic and Pollutant Gas Emissions (PGE) parameters are also examined in accordance with this nMOF optimized outcomes. In the proposed study, the DG’s (PV and D-FACTS) are planned optimally with reconfiguration incorporating practical loads (industrial, commercial, and residential) using an Adaptive Particle-Swarm Optimization (APSO) approach through coding in MATLAB software. Then the techno-economic and environmental-benefit analysis of the results reveals that the R Loss , Q Loss, cost, and PGE are reduced by 96.58 %, 94.39 %, 78.02 %, and 92.58 % with an improved balanced profile of voltage, LFCLevel, and R N .
