Comprehensive Benefit Evaluation of Incremental Distribution Network Considering Different Operation Modes of Distributed photovoltaic

In the new round of power system reform, the incremental distribution network will bear its own profits and losses in the electricity market competition, and its investment planning will focus more on the profitability of future operations. The reasonable investment and operation mode of the incremental distribution network will affect its overall investment return. This article establishes an economic evaluation model for the investment and operation mode of incremental distribution networks. Considering the cost and operational issues of DPV, and referring to research on existing operational models, the cost-benefit composition of incremental distribution networks under different DPV investment and operational models was analyzed. A comprehensive benefit evaluation model for incremental distribution networks based on different DPV operation modes has been established, and a flowchart for comprehensive benefit analysis of incremental distribution networks including DPV has been proposed. On this basis, through case analysis, evaluate the comprehensive benefits under different modes, and select the optimal incremental distribution network investment and operation mode.
