Abstract
Distribution network access is the procedure of connecting new demand and generation to the existing distribution network. Given the large numbers of distributed generators (DGs) requesting access of various capacities at different places, it is challenging for distribution network operators (DNOs) to decide how much the new generation and demand should be connected at each node, given a certain target of total amounts to be connected each year. In this paper, an optimal planning method of distribution network access is proposed to enable DNOs to decide the optimal amount of new demand and generation to be connected at each node across the network. The objective is to maximize the economic benefits of deferring future network reinforcement, by minimizing the net present value of the reinforcement investment given certain load and generation growth rates. The impact of the newly connected demand and generation on future reinforcement is modelled via a feasible operation region-based approach, considering both active and reactive power. Simulation results on a 13-node feeder selected from the 11kV UKGDS distribution system reveal the validity of the proposed method.
