Maximizing the consumption of renewable energy while ensuring the safe and economic operation of distribution networks has become an urgent issue.Firstly,the renewable energy output and load on the nodes are aggregated into net loads,and their uncertainties are described in the form of intervals.Meanwhile,the mapping of the regulation capacity in the system onto the nodes is described as intervals with optimizable endpoints,and the common part between the regulation capacity intervals and the net load disturbance intervals reflects the acceptable domain for net load disturbances at that node.Then,based on priority goal planning,a three-tier optimization model is constructed,aiming to maximize the acceptable domain of net load disturbances,minimize the total operational cost of the distribution network,and minimize voltage deviations,while considering the uncertainty of net loads.This results in an optimized solution that comprehensively considers the maximization of renewable energy consumption,reasonable operational costs,and minimal node voltage fluctuations,ensuring the safety,reliability,and economy of distribution network operation.Finally,the effectiveness of the proposed model and method is verified through a case study based on a modified IEEE 33-node distribution network.
