“…The cost and emission coefficient of thermal units are shown in Table 1 (Luo et al, 2014;Yin et al, 2019). The adjustment range of the output of a hydro-electric unit within a certain period can directly reach the maximum output from the shutdown state, without considering the constraints of climbing speed and minimum startup/shutdown time.…”

“…With the proposal of the national "30•60″dual carbon targets (Guo et al, 2022;Zhou et al, 2022), the continuous promoting of the industrial and energy structure adjustment, the advocacy of green, environmentally friendly, and low-carbon lifestyles, as well as the acceleration construction of the new type power system featuring new energy (Wang et al, 2019;Hu et al, 2021;Wang et al, 2022), have pointed out the direction for the development of the energy and power industry. However, since the new energy possesses the characteristics of randomness, fluctuation, and intermittency (Teleke et al, 2010;Da Cunha et al, 2021;Yang et al, 2022), its large-scale and high proportion of access has posed great threat on the operational economy and power supply reliability of the power system (Yin et al, 2019). At present, the urgent need on the improvement of the new energy consumption rate, the source-grid-load-storage link coordination, and the complementarity of various types of power sources is becoming increasingly prominent.…”

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.
