“…DSTATCOM is predicted to play significant role in the radial distribution systems due to the increasing power system load. Optimum allocation of DSTAT-COM maximizes the load ability, power loss minimization, stability enhancement, reactive power compensation and power quality enhancement such as voltage regulation, voltage balancing a flicker suppression system [6].…”

This paper proposes a new method of scheduling for optimal placement and sizing of Distribution STATic COMpensator in the radial distribution networks to minimize the power loss. In the proposed method Voltage Stability Index is used to search the optimal placement for installation of DSTATCOM. Optimal size of DSTATCOM is found by using bat algorithm. The feeder loads are varied by linearly from light load to peak load with a step size of 1%. In each load step, the optimal placement and sizing for DSTATCOM are calculated. By using the Curve Fitting Technique, the optimal sizing for DSTATCOM per load level is formulated in the form of generalized equation. The proposed approach will help the Distribution Network Operators to select the DSTATCOM size according to the load changes. To check the feasibility of the proposed method, system has been tested on two standard buses such as IEEE 33 and 69 bus radial distribution systems.Ó 2015 Faculty of Engineering, Ain Shams University.

“…To resolve above-mentioned drawbacks DFACTS are used in distribution systems to compensate the reactive power requirements in the distribution networks (Jazebi, Hosseinian, & Vahidi, 2011;Taher & Afsari, 2014). Distribution STATic COMpensator (DSTATCOM) is a notable DFACTS device which has been used to enhance the distribution system efficiency and reliability by providing reactive power support to reduce the total line losses and to enhance the voltage profile (Ledwich & Ghosh, 2002;Sensarma, Padiyar, & Ramanarayanan, 2001;Wasiak, Mienski, Pawelek, & Gburczyk, 2007).…”

In this proposed study, a new long term scheduling is proposed for simultaneous placement of Distributed Generation (DG) and Distribution STATic COMpensator (DSTATCOM) in the radial distribution networks. The proposed work has a unique multi-objective function which consists of minimizing power loss, and total voltage deviation (TVD), as well as maximizing the voltage stability index (VSI) subject to equality and inequality system constraints. The multi-objective problem has been solved by a novel metaheuristic optimization algorithm called as lightning search algorithm (LSA). In the proposed approach, the feeder loads are varied linearly from light load (0.5) to peak load (1.6) with a step size of 1%. In each load step, the optimal sizing for DG and DSTATCOM are calculated by LSA. Through curve fitting technique (CFT), the optimal sizing for both DG and DSTATCOM per load level is formulated in the form of generalized equation. The proposed generalized equation will help the distribution network operators (DNOs) to select the DG and DSTATCOM sizes according to the load changes. The proposed method is tested on two test systems of 33-bus and 69-bus in different cases.

In this paper, a new stochastic structure is described to model the uncertainty effect of the active and reactive loads in the DSTATCOM allocation and sizing problem. The proposed technique has 2m+1 point estimate method (PEM) to trap the uncertainty associated with the expected error of the loads. The objectives are minimization of the total active power losses which diminish the voltage deviation of the buses. Other than that, a new optimization algorithm based on the bat algorithm (BA) is presented to search the problem space globally. Also, the idea of interactive fuzzy satisfying method is applied in the multiobjective formulation to provide a proper balance between the optimization of the objective functions. In the end, the proposed method is tested on the 69-bus IEEE distribution system to validate its feasibility and effective performance.
