Optimal Planning of Distribution Network with DSTATCOM and WTDG using RTO Technique

In this paper, rooted tree optimization (RTO) technique is proposed to solve the optimum deployment problem of distributed static-compensator (DSTATCOM) and wind turbine type distributed generation (WTDG) in distribution network (DN) to enhance voltage profile, reduce loss, maximize economic benefit, and decrease level of pollution. To model the system properly, time-wise variation of both the system load and WTDG's power output are taken into account. Logical formulas are proposed to address the techno-economic and environmental impacts of the devices. The proposed method is tested on 33-bus DN and the obtained results validate the effectiveness of the present strategic methodology when compared with other algorithms. Also, a comparative performance analysis is carried out between DSTATCOM and WTDG, which will help the power industry to choose the most suitable one.
