Abstract:

For raising the initiatives to supply clean and green energy globally, many renewable distributed generations are attached to the network. Power losses, voltage profile maintenance and environmental pollution are the most significant restrictions, which hinder the existing power system. Random penetration of the distributed generation in the existing network can cause severe problems like voltage instability, increase in power losses, system islanding, reverse power flows, environment pollution, etc. Therefore, for clean and green energy, optimal penetration of eco-friendly renewable distribut

The suggested methodology makes use of a hybrid optimization approach that blends fuzzy logic with the Particle Swarm Optimization (PSO) and Golden Section Search Algorithm (GSS). To evaluate the effectiveness and robustness of the suggested method, the study focuses on the IEEE-15 bus and IEEE-69 bus systems as test cases.

Radial Distribution System (RDS) suffer from high real power losses and lower bus voltages. Distribution System Reconfiguration (DSR) and Optimal Capacitor Placement (OCP) techniques are ones of the most economic and efficient approaches for loss reduction and voltage profile improvement while satisfy RDS constraints. The advantages of these two approaches can be concentrated using of both techniques together. In this study two techniques are used in different ways.

Abstract:

Power loss and voltage instability are major problems in distribution systems. However, these problems are typically mitigated by efficient network reconfiguration, including the integration of distributed generation (DG) units in the distribution network. In this regard, the optimal placement and sizing of DGs are crucial. Otherwise, the network performance will be degraded. This study is conducted to optimally locate and sizing of DGs into a radial distribution network before and after reconfiguration.

The electrical distribution system suffers from problems of rising power losses higher than the transmission system and voltage drop. One of the important solutions to improve the voltage profile and to reduce the electrical distribution system losses is the reactive power compensation which is based on the optimum choice of position and capacitor size in the network.

This paper presents an alternative methodology to obtain the precise amount of shunt reactive power compensation in order to simultaneously reduce the total reactive power losses, improve the voltage profile and increase the loading margin of power systems. The amount of shunt reactive power compensation to be allocated is determined based on the curve of the total reactive power losses versus the voltage magnitude of a chosen bus. The best places for shunt reactive compensation are defined by the load bus participation factors of the critical mode provided by the static modal analysis. Simula
