Abstract

The criteria of optimal voltage regulation in the electrical distribution network (EDN) with a source of dispersed generation (SDG) were formulated, if they belong to either one or different owners, taking into account the peculiarities of voltage regulation by means of the SDG and the OLTC system of the transformer. It was found out that under the conditions of economic unprofitability of voltage regulation, in accordance with the above criteria, the owners should take up coordinated work – the general objective function of voltage regulation to improve the effectiveness of regulation and achieve cost-effectiveness. The criteria of optimal voltage regulation if EDN and SDG belong to one owner were formulated. If their work becomes coordinated it is necessary to know exactly which transformer must be regulated; so a transformer with OLTC system should be chosen. Selection sequence is based on the calculation of the sensitivity of the voltage at the nodes within SDG with respect to OLTC position. The proposed OLTC system and SDG coordinated work makes it possible to increase the effectiveness of voltage regulation in the EDN with SDG under different conditions of ownership and increase the economic profitability of regulation
