This paper presents a new hybrid chemical reaction optimization (HCRO) approach which is based on chemical reaction optimization (CRO) and differential evolution (DE), to find the optimal placement and parameter setting of Static Synchronous Compensator (STATCOM) which is a shunt compensating Facts device to achieve the performance of power system network optimally. However, getting optimal solution of ORPD problem is a cumbersome task for the researchers. This paper presents for optimal allocation of a static synchronous compensator (STATCOM) using hybrid chemical reaction optimization to minimize the transmission loss and voltage deviation in a power system. Moreover, to establish the superiority, the results under simulation reveals that the proposed HCRO technique is superior ascompared to the CRO and DE. The proposed algorithm is implemented and tested successfully on IEEE 30-bus test power system. It is found that the results obtained by the proposed HCRO technique are superior to those obtained by other discussed algorithms.

This paper presents a scheme for Load frequency control (LFC) of interconnected multi-area multi source power generation. The conventional multi-area LFC system is modified to take into account the effect of unilateral contracts on the dynamics. The classes of extensive deregulated cases are presented by examining the closed loop performance of the model. The results under simulation reveals that the designed power system model may a feasible one and the proposed algorithm may be a well-known optimization technique under these circumstances of Oppositional Krill Herd algorithm(OKHA). The performances of proportional integral-derivative (PID) are evaluated for the proposed AGC system. The gain of the controllers and parameters of speed regulation are optimized using differential evolution (DE) algorithm.
