Flexible Capacitor Placement To Manage Disaster In Distributed Generation: A Fuzzy Technique

This work is focused on placement and sizing of capacitors with effectiveness to maintain voltage profile and power savings.. A fuzzy expert system is considered for finding optimal location & size of capacitors. This scheme is tested on IEEE 14 bus system. The Data is analyzed for voltage profile, active and reactive power savings. The evaluation of performance for load flow on base load, active power losses and minimum voltage are considered. The bus is compensated with reactive power injection equivalent to self reactive load, then checked Power loss Index, Voltage profile, Active power and Reactive power losses for each cases. The most suitable size and location of the capacitor is achieved under proposed scheme. It shows a significant improvement for maintaining system voltage and frequency. Net savings of energy in percentage due to compensation is calculated.
