Adaptability Analysis of Distribution Network to Distributed Generation Considering Hosting Capacity and Absorption Capability

With the increasing penetration of distributed generation in the distribution network, it has become important to evaluate the adaptability of the distribution network to distributed generation. The adaptability of the power grid to DG can be characterized by “hosting capacity” and “absorption capability”. The existing researches mainly focus on the evaluation of either " hosting capacity" or “absorption capability”, and does not involve the active transformation of the distribution network. In this paper, a top-down evaluation method is proposed to evaluate the hosting capacity of distribution network. Then the paper puts forward the reconstruction scheme of the existing power grid and gives the best operation strategy, which can make the power grid absorb DG as much as possible during operation.
