Optimal voltage control in distribution feeders with large penetration of wind
Department of Electrical and Computer Engineering, Center for Cyber-Physical Systems
This paper develops coordinated voltage control with high penetration of wind in power distribution systems. In the proposed method, daily schedule of optimal voltage profiles are determined by using optimization technique based on predicted values of load demand and by controlling tap positions of regulators, switched capacitors, and reactive power outputs of the inverters. In this paper, three optimal voltage control models are developed: the first model uses capacitors as control devices; the second model uses capacitors and tap changers of voltage regulators; and the third model includes the inverters of the wind turbines as well. We use a recently developed heuristic, Sine-cosine algorithm, to solve the optimal voltage control problems. The case studies carried out on a modified 33-node feeder shows the effectiveness of the proposed optimization models in controlling the voltages in distribution feeders.
