PSO based optimal control for maximizing PV penetration

Recent studies suggest that in medium and long terms, distributed solar photo-voltaic generator (SPVG) will become commercially so attractive that large-scale implementation of this type can be seen in many parts of the world. The increase in the amount of renewable energy will cause stability and security issues in power system. An effective method is used to find out the maximum allowable penetration of renewable energy, in this case Solar PV energy. IEEE 14 bus dynamic model is considered for conducting penetration analysis. Particle swarm optimization (PSO) based algorithm to find the optimal location and maximum penetration at the optimal location is proposed in this paper. Results present the maximum system penetration, optimal location and setting of SPVG, maximum safe bus loading beyond which system becomes unstable.
