    Abstract:

    To address the insufficient equipment coordination and inadequate consideration of distribution network conditions and uncertainty risks in the planning of photovoltaic-energy storage-charging stations (PECS), an economic and low-carbon coordinated configuration model for PECS is proposed considering uncertainty risks. A coordinated planning model is established by incorporating power prices and low-carbon demand response, PECS daily operation status and distribution network power flow constraints. Based on typical scenarios generated by K-means clustering, conditional value-at-risk is employed to quantify the PECS risk costs from photovoltaic output and charging load uncertainties. The constructed model is reformulated via product linearization and second-order conic relaxation into a unified model for accurate solution by commercial solvers. Simulation results verify that the proposed model improves the planning economy of the PECS, meets the high-efficiency and low-carbon demands of the distribution network operation, and balances economic costs, environmental benefits and risk costs.
