Keywords:Active power losses Multi-objective optimal reactive power dispatch (MO-ORPD) Scenario-based uncertainty modeling Stochastic programming Voltage stability Wind farms (WFs) a b s t r a c t Optimal reactive power dispatch (ORPD) problem is an important problem in the operation of power systems. It is a nonlinear and mixed integer programming problem, which determines optimal values for control parameters of reactive power producers to optimize specific objective functions while satisfying several technical constraints. In this paper, stochastic multi-objective ORPD (SMO-ORPD) problem is studied in a wind integrated power system considering the loads and wind power generation uncertainties. The proposed multi objective optimization problem is solved using ε-constraint method, and fuzzy satisfying approach is employed to select the best compromise solution. Two different objective functions are considered as follow: 1) minimization of the active power losses and 2) minimization of the voltage stability index (named L-index). In this paper VAR compensation devices are modeled as discrete variables. Moreover, to evaluate the performance of the proposed method for solution of multi-objective problem, the obtained results for deterministic case (DMO-ORPD), are compared with the available methods in literature. The proposed method is examined on the IEEE-57 bus system. The proposed models are implemented in GAMS environment. The numerical results substantiate the capability of the proposed SMO-ORPD problem to deal with uncertainties and to determine the best settings of control variables.

“…As IEEE 1547 [5], [6] does not allow to regulate the voltage at the PCC actively, in this paper, the location of the D-STATCOM is determined based on the weak bus oriented STATCOM placement planning to increase system's reactive power margin [18]. According to [18], the suitable location of the D-STATCOM for the present study is bus 15 which is the most critical bus of this network.…”

This paper proposes an optimal linear quadratic Gaussian (LQG) controller for D-STATCOM to improve the dynamic performance of distribution networks with photovoltaic generators. The controller is designed based on the H ∞ norm of the uncertain system. The change in system model due to the variation of load compositions in the composite load is considered as an uncertain term in the design algorithm. The performance of the designed controller is demonstrated on a widely used test system. Simulation results indicate that the proposed controller can be a potential solution for improving the voltage stability of distribution networks.

“…Alonso et al (2006); Ettehadi et al (2012) and Abri et al (2013) explained the use of optimization techniques to improve the stability margin by sizing and location of Distributed Generation (DG). The effect on voltage stability due to variation in load is explained by Roy et al (2013) and Zamora et al (2014) by using PV and QV curves. PV and QV curves represent the variation of voltage with active power and reactive power of the load respectively.…”
