Considering that the benefits of hydropower stations from regulating and consuming new energy are restricted during the dry season due to the inadequate regulation capacity, this paper focuses on the accommodation capacity evaluation of hydropower for wind‐ photovoltaic (PV, for short) power generation in different supply‐grid‐load conditions. First, the factors that influence hydropower stations' accommodation capacity were initially examined in this study, in terms of power supply, power grid, and load. Then, two new indices, namely the regulatory factor of installed capacity and the regulatory factor of electric quantity, were put forward to evaluate the capacity of hydropower for accommodating wind‐PV. To reduce the peak regulation burden on the power grid and encourage the consumption of clean energy, a two‐objective optimization model with maximum source‐load matching and clean energy consumption was devised. And a two‐tier binary algorithm and progressive optimization coupled strategy was proposed to solve the model. Finally, the cascade hydropower stations in the north Panxi section of the Yalong River and the surrounding wind farm and PV power stations were taken as examples to examine the sensitivity of the factors. The results show that with each 5% increase in the regulatory electric quantity, the regulatable installed wind‐PV capacity and consumable wind‐PV electric quantity were increased by 7.57% and 8.21%, respectively, rank only second to transmission capacity. Considering the large investment required for transmission channel expansion, this result reveals that the most effective and economical way to promote wind‐PV consumption is to increase the regulated electric quantity of hydropower stations in the river basin.

In order to reduce the impact of load fluctuation brought by new energy interconnection, the operation cost of power grid is increased. Considering the characteristics of load fluctuation, this paper studies a new energy grid source load interval coordination scheduling method. Based on the characteristics of source load fluctuation and demand side load fluctuation of new energy grid, the dispatching principle is established. In this paper, the flexible operation region of new energy grid is calculated, and the target function of power grid source load interval is constructed. Numerical results show that the proposed method can improve the economy of energy storage unit and power system, and the comprehensive benefit is positive in different scenarios.

With the goal of “double carbon,” wind power and PV are connected to the grid on a large scale, which poses a great challenge to the safe operation of the grid. The synergistic optimization of “hydro-wind-PV hybrid systems” can bring into play the ability of coordination and mutual assistance between different types of power sources, which is one of the important measures to increase the safe operation of the power grid and reduce abandoned wind and photovoltaic power. Based on the analysis of the characteristics of hydro-wind-PV power, the “hydro-wind-PV” integrated network-source cooperative optimization scheduling model is constructed to maximize the source-load matching and the consumption of clean energy. Finally, the results of a case study of a hydropower-wind power-photovoltaic cluster project in southwest China are used to verify the rationality and feasibility of the model.
