Special Issue Information

Dear Colleagues,

In recent decades, the excessive utilization of traditional fossil fuels has led to serious environmental pollution and has hastened the climate crisis. Substituting fossil fuels with renewable energy like wind and photovoltaic power can, to a certain degree, ease this crisis. Against this backdrop, the installed capacity and power generation of renewable energy sources are constantly on the rise.

Nevertheless, with the swift progress of renewable energy technologies, because of the intrinsic intermittency, volatility, and unpredictability, the direct integration of wind power and photovoltaics poses challenges to the safe and stable operation of the power grid.

Therefore, to achieve the integration of large-scale renewable energy generations, combining flexible power resources (such as hydro) and renewable energy into a complementary power generation system is an effective means to promote the accommodation of new energy connected to the grid. Renewable energy does not produce pollutants and contributes to sustainable society and economic growth with much lower carbon emissions. Thus, the coordination of flexible resources and renewable energy is preferred as an optional power source for replacing fossil fuels to alleviate the weather crisis and achieve cleaner and more sustainable energy systems. This Special Issue aims to present the latest advancements in renewable energy technologies and sustainability, with a particular focus on the operation and control of power grids with the high penetration of renewable energy generations.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  1. Prediction, modeling, and uncertainty analysis of renewable energy generation;
  2. Optimal design and sizing for off-grid hybrid energy systems;
  3. Novel renewable energy-dominated hybrid systems;
  4. Efficient and secure integration of massive renewable energy resources;
  5. Operation and control of renewable energy resources;
  6. Sustainable policies for renewable energy development;
  7. Market structure design for boosting the penetration of renewables;
  8. Energy trading of renewable energy resources;
  9. Situational awareness and risk management of renewables-dominated power systems;
  10. Development of novel approaches for the modeling and simulation of hybrid energy technologies;
  11. Coordinated planning and design for renewable energy systems;
  12. Variable power transmission technologies for renewable energy generation;
  13. Resilient planning and operation for renewables-dominated power systems.

We look forward to receiving your contributions.

This paper examines how the slope of the merit-order curve and the share of non-zero-dollar dispatched energy affect photovoltaic (PV) price cannibalization and the declining market value of all generation types. Using historical merit-order data from Alberta, Canada—during its coal-to-gas transition—we simulated the introduction of zero-marginal-cost PV offers. The increased PV penetration rapidly suppresses midday electricity prices, forming a “duck curve” that challenges solar project economics. Emission reductions improve with rising carbon prices, indicating environmental benefits despite declining market revenues. Years with steeper merit-order slopes and lower non-zero-dollar dispatch shares show intensified price cannibalization and a reduced PV market value. The integration of battery storage alongside PV significantly flattened daily price profiles—raising the trough prices during charging and lowering the highest prices during discharging. While this reduces price volatility, it also diminishes the market value of all generation types, as batteries discharge at zero marginal cost during high-price hours. Battery arbitrage remains limited in low- and moderate-price regimes but becomes more profitable under high-price regimes. Overall, these dynamics underscore the challenges of integrating large-scale PV in energy-only markets, where price cannibalization erodes long-term investment signals for clean energy technologies. These insights inform sustainable energy policy design aimed at supporting decarbonization, and investment viability in liberalized electricity markets. Full article
