Optimal Allocation of Combined DG and DSTATCOM for Enhancement of Voltage Stability in Radial Distribution Networks

Received Date:03 May 2023, Accepted Date:01 August 2023, Published Date:19 September 2023


Objectives: To improve the voltage profile, minimize the network power loss and enhance the stability of the Redial Distribution Systems (RDS). Methods: A novel and successful meta-heuristic method of Group Teaching Optimization (GTO) algorithm is proposed to evolve the solution of voltage stability in RDS. The effective compensating devices of DG and DSTATCOM are used for increasing the voltage profile and reducing the system losses. The VSI is also calculated to predetermine the best position of the two compensating devices Findings: GTO is effective in finding the optimal position and sizing of compensating devices. To evaluate the applicability and efficiency of GTO it’s tested on standard IEEE 34 and 69 note RDS. Implementation of GTO algorithm is made using MATLAB software. The simulated results of voltage profile, VSI, Network loss, optimal sizing and position of the DG and DSTATCOM are displayed. Novelty: GTO is a parameter less algorithm; so it has more searching ability, provides accurate results and robustness. Obtained results are also compared with other soft computing methods such as PSO and CSA to prove the performance of the GTO method.
