Placement and Sizing of Capacitor and Renewable DG for Loss Minimization at Different Load Levels Using Matlab/Simulink

The proposed paper presents a simple methodology for active power loss minimization and it is carried through optimal placement and sizing of capacitor and Distributed Generation (DG).The placement of capacitor and DG is done through loss sensitivity factor which is one of the concepts in the field of distribution system and it is used to identify the potential nodes. In our proposed method we have considered a single capacitor and single DG for placement. After identifying the potential node, the capacitor sizing is done by calculating compensative reactive power (����) for different load levels. Next, the sizing of distributed generation is carried on by considering different penetration levels i.e., from 10% to 90% of the total system active power load at different load levels. So, finally we reach to a conclusion of loss minimization at some particular penetration level for different load levels. Thus, the reactive power compensation through capacitor and the active power injection from renewable Distributed Generation which is placed near to the load centres contributes for system voltage support and active power loss minimization. Nevertheless, the acceptable method also meet the necessities like reasonable speed, storage, highly authentic, assumed versatility and simplicity. Finally the proposed methodology is implemented through MATLAB/SIMULINK on 12, 15, 33 bus radial distribution system.
