Special Issue Information

Dear Colleagues,

The development and utilization of clean renewable energy is a significant measure to achieve carbon peaking and carbon neutrality goals. With the successive planning and construction of a large number of hydro-wind-solar complementary clean energy bases, not only the inherent stochastic fluctuation of water, wind and solar resources, but also hydropower station, wind power station and solar power station groups with different spatial locations lead to the temporal and spatial variation mechanism of water, wind and solar resources in the basin becoming more complicated. In addition, global climate change and human activities have sharply changed the process and features of resources and have exerted a huge impact on power systems. As a result, it is difficult to predict future resource conditions precisely and synergize hybrid power systems. Thus, energy system management has emerged as a hot topic of scientific research and technological innovation that many scholars have been keen to explore in recent years. It is necessary to develop effective methods and technologies for improving the utilization efficiency of the hydro-wind-solar power systems. 

In this context, researchers can submit their valuable research to this Special Issue entitled “Advanced Research on Hydro-Wind-Solar Hybrid Power Systems”. Original field and experimental research papers, review papers, and case studies are invited for submission in the context of managements on Hydro-Wind-Solar Hybrid Power Systems, and other related problems. Some related topics may include, but are not limited to:

  • Analysis of spatio-temporal evolution characteristics of renewable resources;
  • Multi-time scale joint stochastic simulation of hydro-wind-solar scenarios;
  • Multi-step prediction method of resources or power generation;
  • Multi-objective hybrid power systems operation optimization methods;
  • Long-term complementary operation rules for hydro-wind-solar hybrid power systems;
  • Daily generation scheduling of hydro-wind-solar hybrid power systems;
  • Economic operation of hydro-wind-solar hybrid power systems;
  • Robust operation of hydro-wind-solar hybrid power systems to cope with emergencies under extreme weather scenario;
  • Adaptive decision-making of hydro-wind-solar hybrid power systems under changing environment;
  • Resilience of hydro-wind-solar hybrid power systems under climate change;
  • Risk analysis of hydro-wind-solar hybrid power systems considering multiple uncertainties.

To enhance the efficiency of solving the optimal operation model for cascade reservoirs, this paper first constructed an optimal operation model of cascade reservoirs. The model comprehensively considered the ecological flow, the guaranteed output of hydroelectric power plants, and the relaxation constraints of the water level at the end of water supply and storage period. The relaxation constraints refer to two relaxation variable constraints, which are used to ensure that the water levels decline in the water supply period and rise in the water storage periods. At the same time, to avoid the challenges of “dimension disaster” and susceptibility to local optima commonly encountered in existing optimization algorithms when resolving the above model, a novel optimization algorithm, M-IWO-ODDDP, derived from the optimization principles of the Invasive Weed Optimization (IWO) and Discrete Differential Dynamic Programming (DDDP) algorithms, was proposed in this paper. The 11 cascade hydropower stations in the Wujiang River basin were used as a case study, and the results showed that the water-level dispatching process exhibited a high degree of conformity with the actual dispatching process during both the water supply and storage periods. Furthermore, the output calculation results based on the M-IWO-ODDDP algorithm were 3.94% and 0.30% higher than the actual output and ODDDP calculation results, respectively, while reducing water abandonment by 21.58% and 4.07%.

A hydro–solar hybrid system is an important solution for expanding renewable generation capacity under the percepts of the energy transition. This type of association allows for the coordinated dispatch of solar and hydropower plants, resulting in operational benefits in terms of energy generation and reservoir management, that is, the better use of available water and energy resources. As in this case, the operation of the hydropower plant is associated with the cascade in which it operates, when it is hybridized (for example, by associating with a solar power plant), in addition to local changes, there are impacts on the operating conditions of the other hydropower plants in the same cascade. From such a perspective, this study presents an energy system management model for hybrid power plants composed of hydro and solar sources, aiming to optimize the joint operation and measure the operational consequences at the local level and in the cascade. The results from a case study of a hydro–solar power plant hybridization in the Tietê River (Brazil) revealed increased energy production and improvement in the operating conditions of the cascade’s reservoirs, while the grid capacity was found to be an important constraint that limits the capture of synergies resulting from the generation sources complementarity and thus on the benefits to the cascade.
