Abstract
Background: Recently, the incorporation of Distributed Static-Compensator and Distributed Generation in distribution system has become essential for the distribution companies to be adopted for the overall system benefit. In this study, the optimal sizing and siting of these devices are conducted in distribution system using Modified Shuffled Frog Leaping Algorithm to maximize the technical, economic, and environmental benefits.
Methods: New frog leaping rules are proposed in the Modified Shuffled Frog Leaping Algorithm to enhance the overall performance of the algorithm. Innovative formulas such as Revamp Voltage Stability Index, Benefit Cost Ratio, and Environmental Benefit Index are formulated to assess the technical, economic, and environmental aspects of the device. To judge the feasibility and accuracy of the proposed technique, it is applied on 33-bus and 69-bus distribution system considering different load models and after that, the performances of the devices are analyzed on the basis of the techno-economic and environmental impacts.
Results: Furthermore, the overall system benefit is also investigated after placing both the devices simultaneously. The proposed method is compared with other evolutionary algorithms to prove its superiority.
Conclusion: This entire analysis will facilitate the power industry to choose an optimal strategy for the overall benefit of the system.
Keywords: Benefit cost ratio, distributed generation, distributed static-compensator, environmental benefit index, modified shuffled frog leaping algorithm, optimal placement, revamp voltage stability index.
