Stochastic Estimation and Enhancement of Voltage Stability Margin considering Load and Wind Power Intermittencies

When operating deregulated electricity systems, optimal reactive power dispatch is a critical responsibility. This issue of reactive power is an integer non-linear formulation that determines several optimum values for maintaining reactive power in the system while satisfying various constraints in a sequential manner. This work investigates a multi-objective stochastic problem of reactive power dispatch that takes into account loads and wind uncertainties. The optimization formulation is clarified using a fuzzy technique that finds the best optimum solution while taking restrictions into account. Compensation devices are represented as discrete variables in this paper. The proposed method is tested on a standard IEEE-57 bus system. The investigation's findings confirm that the proposed methodology is capable of dealing with intermittencies and gives superior control variable solutions.
