“…Literature (Wang et al, 2023) in order to address the issues of randomness and volatility caused by the high integration of renewable energy into the grid, focuses on the wind-solar-hydro energy storage joint optimal scheduling strategy of a new power system using an improved particle swarm optimization algorithm to enhance renewable energy utilization. Literature (Gejirifu et al, 2022;Gu et al, 2022) take the lowest comprehensive operation cost and the largest amount of new energy consumption as the objective function, and establish a joint scheduling model to realize the multi-energy complementary operation of the wind-photovoltaicthermal-energy storage system. Literature (Liantao et al, 2021) takes the maximum economic benefits of hybrid energy system as the objective function, builds a day-ahead scheduling optimization strategy for power systems with pumped storage, wind power, photovoltaic and thermal-electricity units, aims at reducing pollution control costs and improving the output capacity and stability of thermal power units.…”

The linkage, coordination, and complementary cooperation of energy supply can improve the efficiency of transportation and utilization. At present, the level of new energy consumption needs to be improved, the coordination of the source network load storage link is insufficient, and the insufficient complementarity of various types of power sources in the power system. This article fully explores the differences and complementarities of various types of wind-solar-hydro-thermal-storage power sources, a hierarchical environmental and economic dispatch model for the power system has been established. Among them, the upper level model takes the flexible consumption of new energy as the optimization goal, the middle level model uses a combination of hydropower station and energy storage to minimizes the fluctuation variance and peak-to-valley difference of the net load curve, the lower level model aims to achieve optimal environmental and economic benefits of the power system, comprehensively considers the coal consumption cost, startup and shutdown cost, energy storage operation cost, and pollutant emissions of thermal power units, determines the startup and shutdown mode and output power of thermal power units. Finally, an improved IEEE 6-machine 30-node system is used as an example for simulation analysis, the results show that after applying the proposed hierarchical environmental and economic dispatch strategy of the power system, the fluctuation variance and the peak-to-valley difference of the net load curve have been reduced by 46.3% and 31.5%, respectively, and the environmental and economic benefits of the system is improved by 5.1% compared with the traditional economic dispatch strategy. It can meet the requirements of energy system cleaning and decarbonization while improving the operation economy, which verifies the effectiveness of the proposed environmental economic dispatch model.

“…Due to the intermittent and fluctuating nature of renewable energy sources, connecting high-capacity wind and photovoltaic power generation into the power system will seriously affect the power quality and the stable operation of the grid (Sezer et al, 2019). The scheduling and operation of various power sources, including wind/PV/ hydro/thermal and storage, are of increasing concern (An et al, 2020;Gejirifu et al, 2022). Based on this background, the synergistic operation of PV/wind energy with other renewable energy sources (e.g., hydropower or energy storage) is a current research hot spot.…”

In order to achieve the economic consumption of renewable energy in a multi-energy power system including wind/PV/hydropower and energy storage, a two-tier coordinated optimal scheduling method based on generative adversarial network (GAN) scenario generation is proposed in this paper. First, an upper-tier optimization model for the operation of the load and storage system is established to achieve the objective of minimizing the load fluctuation and the cost of energy storage plants. Furthermore, a lower-tier optimization model to minimize the system operation cost and tide risk is established for the optimization operation of renewable energy generation. Second, an improved generative adversarial network is proposed to generate the operation scenes for evaluating the uncertainty characteristics of the wind and photovoltaic (PV) generation. Then, an improved coati optimization algorithm (COA) is used to solve the proposed optimization problem. Finally, the IEEE 30-bus system is selected as the example system for verifying the proposed method. The simulation results corroborate the validity and feasibility of the proposed method.
