Unified Power Flow Controller (UPFC) is one of the most efficient FACTS devices that can be individually or combinatorial on all effective parameters in the transmission power of the transmission lines. With the flexibility of effective parameters in power passage, the power system operation can be improved. in this study, the optimization algorithm based on location and optimal capacity of UPFC has been proposed to improve the stability of power system stability. The proposed method innovation is demonstrated by improving search functionality, stochastic reduction, and complexity reduction. In this regard, the generator error affects power system operation constraints, including voltage, real and reactive power dissipation, as well as computational cost. The UPFC modeling is a power injection and load injection model of the Newton - Raphson method. Power system operation conditions are formulated with the objective of minimizing the power loss, minimization of voltage variation, and installation cost of UPFC. in matlab software, an optimization algorithm for solving the problem on the ieee 14 and 30 bus test systems is implemented and the results of investigation are compared with other methods. |
