Optimizing Distributed Generation Placement and Sizing using Genetic Algorithm, Particle Swarm Optimization, and PSO-Sim.

Problem Definition

The existing literature has highlighted several shortcomings in the current approaches used for determining the optimal size and location of Distributed Generators (DGs) within distribution systems. While Evolutionary and meta-heuristic optimization algorithms like ABC, CSOS, WHO, and ICA have been employed in the past, these methods fall short in addressing all technical, environmental, and economic issues. The lack of a comprehensive approach hinders the flexibility of distribution systems and ultimately results in suboptimal outcomes, failing to sufficiently enhance voltage stability and minimize power losses. The identified limitations underscore the critical need for a new approach that can effectively allocate DG units to maximize voltage stability and minimize power losses. This new approach must address the shortcomings of existing methods and provide a more holistic solution that considers all aspects of distribution system operation.

By developing a more efficient and effective strategy for the optimal allocation of DG units, it is possible to achieve significant improvements in voltage stability and power loss reduction within distribution systems.

Objective

The objective is to develop a hybrid method using Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) to determine the optimal size and location of Distributed Generation (DG) units in distribution systems. This approach aims to enhance voltage stability, minimize power losses, and address the limitations of existing methods by offering robustness, support for multi-objective optimization, and easier implementation. By sequentially using GA and PSO algorithms, as well as utilizing the simultaneous placement approach of PSO-Sim, the goal is to improve the overall operation of distribution systems through efficient DG allocation.

Proposed Work

In the proposed work, the focus is on addressing the research gap related to determining the optimal size and location of Distributed Generation (DG) units to enhance the voltage stability and minimize power losses in distribution systems. The existing literature shows that current approaches utilizing Evolutionary and meta-heuristic optimization algorithms have limitations in addressing technical, environmental, and economic issues while providing flexible operation of the distribution system. To overcome these limitations, a hybrid method incorporating Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) is proposed for identifying optimal DG placement locations. The use of PSO, GA, and PSO-Sim algorithms offers advantages such as robustness in handling complex optimization problems, support for multi-objective optimization, and easier implementation with less complexity. The proposed approach involves the sequential use of GA and PSO algorithms, as well as the simultaneous placement offered by the PSO-Sim approach.

GA eliminates the need for derivative calculations, supports multi-objective optimization, and is robust against local minima/maxima. PSO provides a simpler implementation and the PSO-Sim approach allows for simultaneous placement of DG units. By utilizing these three approaches, the goal is to improve voltage stability and minimize power losses through optimal placement of DG units. The effectiveness of each approach will be evaluated based on their impact on voltage stability and power losses in distribution systems.
