“…Therefore, the existing results are relatively simple. Additionally, in smart distribution networks, distribution network reconfiguration is a nonlinear programming problem based on switch combinations, where the optimization of the network structure is achieved by changing the state of the switch [8,9]. To reduce power losses, Zhang et al (2016) [10] conducted distributed power source planning to improve environmental benefits while considering the static reconfiguration of the network and employed intelligent algorithms to solve the problem.…”

Nowadays, the power grid with a high proportion of renewable energy is increasingly popular. Taking a new energy power system including wind power (WP), photovoltaic power (PP), and pumped storage power (PSP) as an example, in order to solve the problem of resource waste such as massive WP-PP abandonment and power losses caused by the randomness and volatility of new energy, this paper establishes a combined power generation model of WP-PP-PSP-thermal power (TP). It achieves the goal of minimum network loss and minimum WP-PP abandonment in the combined power generation system according to the characteristics of PSP and considering various constraints and distribution network reconfiguration. Then, the second-order cone relaxation (SOCR) technology is used to transform the model into a mixed second-order cone programming model. Finally, the design scheme is tested by the improved IEEE 33-bus system, and the effectiveness of the algorithm is analyzed. The results show that peak cutting and valley filling can be realized when PSP energy is added to the WP-PP grid connection system.
