Abstract

[Objectice] In view of the problem that the traditional calculation method for distributed photovoltaic (PV) capacity cannot comprehensively consider the energy absorption capacity of the transmission network and the operational safety of network equipment, this paper proposes a method for constructing and optimally solving the distributed PV capacity interval considering the coordination between the transmission and distribution networks.[Methods] Firstly, at the transmission network level, considering different provincial new energy utilization rates and energy storage configuration ratios, the distributed PV capacity interval is constructed based on time-series simulation of production simulation.Secondly, at the distribution network level, with the goal of optimizing the investment economy of the distribution network, a method for optimally solving the distributed PV capacity and checking the interval is proposed, taking into account the power flow of transmission and distribution networks, power quality, and energy storage charging and discharging constraints.Finally, case studies are conducted in provinces of different regions in China. [Results] The results show that the distributed PV capacity interval and the optimal solution of distributed PV capacity can constrain each other, which can meet both the new energy absorption demand of the transmission network and the reliable operation demand of the transmission and distribution networks. [Conclusions] The proposed method incorporates distributed PV into the provincial supply-demand calculation, considers the impact of the absorption space of all power sources on capacity calculation, scientifically evaluates the accessible margin of the power grid, and provides an important reference for guiding the rational layout of distributed PV.
