Multi-objective Optimization Planning of Total Supply Capability Evaluation in Distribution Network Considering Network Reconfiguration and Demand Response

Abstract

The increasing permeability of flexible loads and development of demand response technology not only promote the flexibility of the distribution network dispatch, but also pose challenges on ensuring total supply capability (TSC) and economy efficiency. To this end, the TSC model with demand response constraints based on power flow calculation in terms of multi-period time-scale is first constructed, while considering the N-1 criterion and topology reconfiguration. Then, a multi-objective optimization programming structure is developed, taking the TSC and operation economy as the objective function. Subsequently, the pareto frontier is introduced to solve the model. Finally, the case study on modified 94 node test system validates the availability and accuracy of the proposed model and approach.
