Cost and Benefit Optimization on Installation of Distribution Feeders Voltage Control Equipment considering Distributed Generations

Abstract

The primary purpose of this study is to explore the impacts of distributed generation (DG) interconnections on distribution systems in Taiwan. To build a DG-friendly distribution system for the development of DGs, a genetic algorithm with Pareto optimality is utilized to analyze the cost and benefit of installing a distribution feeder voltage control equipment that considers DGs. The major objectives include minimizing the total cost of installing the distribution feeder voltage control equipment and maximizing DG utilization. The total cost includes the installation cost and operation cost of the voltage control equipment. The results indicate that the voltage control equipment is important for improving the voltage profile along the feeders, reducing the system power losses, and maximizing the possible installed capacity of DGs. The conclusions from this study are crucial to DG interconnections and for promoting the future development of renewable energy in Taiwan.
