Optimal Location of Capacitors For Voltage Control In Radial Distribution Network By Using PSO Algorithm
This paper proposes a Particle Swarm Optimization method for optimal placement of capacitors in radial distribution system. Because of simple design and low cost radial distribution systems are more popular. But in distribution system, when buses moved away from the substation, the voltage drop increases and losses are also high. Lack of reactive power is the reason for voltage drops and high losses. It is necessary to solve this voltage problem for supply of good quality of power. In this paper series capacitors are used as reactive power compensators. By optimal location and sizing of capacitors voltage can be maintained in permissible limits and also losses can be reduced. In this work, a case study of 6-bus system is considered and comparison of PSO method is made with conventional calculations.
