摘要
Abstract
The superposition of uncertainties in distributed generations and load in distribution network causes difficul?ty in the local consumption of renewable energies. In this paper,to solve the optimization problem of day-ahead dis?patching plan for the distribution network with distributed renewable energies,a dispatching strategy is established in consideration of the interval difference of predicting credibility.By introducing credibility modification,the available re?sources are allocated optimally in different intervals.In this way,a comprehensive control of risk in different intervals can be achieved based on the local consumption of renewable energies. During the solving process,the efficiency of computation is improved through model reconstruction and the construction of initial feasible solutions.A simulation ex?ample based on an IEEE 33-bus system shows that the optimized dispatching strategy can effectively improve the local consumption capacity of renewable energies and reduce the operation risk in the dispatching plan.关键词
