OPTIMAL SEASONAL VOLTAGE CONTROL IN RURAL DISTRIBUTION NETWORKS WITH DISTRIBUTED GENERATORS

This paper proposes a procedure for determining the optimal tap changer positions of off-voltage tap changing transformers in radial rural distributionnetworks in presence of distributed generators (DGs). The procedure is based on spatial network decomposition and as well as bringing down a branchy LV network toan equivalent line. Optimal voltage module values of PV nodes in the optimal seasonal control plan are determined by theapplication of a genetic algorithm. The proposed procedure is examined in two real distribution networks: a radial 33-node network with 11 DGs modeled as PQ nodes and a radial 40-node network with three DGs in total, two of which are modeled as PV nodes and one modeled as a PQ node.
