Hierarchical Dispatch Optimization for Intelligent Community Considering Electricity Evaluation

As an important part of smart grid, intelligent power community is featured with flexible, controllable and two-way interactive. This paper proposes a hierarchical dispatch optimization approach considering the residents' electricity evaluation. Firstly, based on controllable load operation characteristics and electric vehicle driving rules, the model of residents' electricity evaluation system which includes body sense evaluation, travel evaluation and electricity evaluation is established. Next, the optimization with the goals of operator's income, network's fluctuation and residents' electricity evaluation is carried out. It is shown via simulations that the proposed model perform well in practice, and the result shows that the proposed hierarchical dispatch optimization strategy can guarantee the operator's profit and residents' electricity evaluation while suppressing the fluctuation of the distribution network load.
