Optimal Reactive Power Flow in a Deregulated Power System – A Case Study

Optimal reactive power flow is an optimization problem with one or more objective of minimizing the real power losses. The ancillary service for a generator has two components that have been recently recognized, i.e., one for sustaining its own real power communication and the other for providing reactive demand, enhancing system security, and scheming system voltage; and that only the next part should get financial compensation in aggressive power markets. The power flow equations and the inequality constraints of basic system operation are the equality constraints, such as voltage magnitude limits. In this paper planned incorporated technique will be united with fuzzy logic and cuckoo search algorithm. One of the knowledge base intelligence techniques which will be utilized for verifying the generator reactive power operating limits was the fuzzy logic. Cuckoo search is solitary of the optimization algorithms which will be used for optimizing the purpose function parameters. Representative results are presented using the IEEE 30 bus system by using MATLAB working platform and the ORPF presentation will be estimated.
