Special Issue Information

Dear Colleagues,

The global renewable energy market is currently in a phase of explosive growth. By 2030, renewable energy is projected to account for over 60% of global electricity supply. Driven by advancements in renewable energy generation technologies and cost reductions, countries such as China, Europe, North America, and emerging markets like India and Brazil, are actively accelerating investment in clean energy and building robust renewable energy markets. As the scale of renewable energy markets continues to expand globally, profound impacts will be felt across energy infrastructure development, grid safety and dispatch, industrial supply chains, capital investment, technology integration, business model innovations, shifts in consumer energy usage behaviors, and the effectiveness of energy conservation and carbon reduction efforts.

This Special Issue of Energies aims to present and disseminate findings on the impacts, challenges, and opportunities brought about by global renewable energy development to markets such as capital investment, industrial supply chains, business models, and electricity consumption.

Against the backdrop of the full market integration of renewable energy, determining a reasonable proportion between medium- and long-term (MLT) contracts and spot trading has become a core issue in power market reform. Current Chinese policy requires that the share of MLT contracts should not be less than 90%, which helps ensure system security but may suppress the price discovery function of the spot market and limit renewable energy integration. This paper constructs a three-layer model: the first layer describes spot market clearing through Direct Current Optimal Power Flow (DC-OPF), yielding system energy prices and nodal prices; the second layer models bilateral contract decisions between generators and users based on Nash bargaining, incorporating risk preferences via a mean–variance framework; and the third layer introduces two evaluation indicators—contract penetration rate and economic proportion—and applies outer-layer optimization to search for the optimal contract ratio. Parameters are calibrated using coal prices, wind speed, solar irradiance, and load data, with numerical solutions obtained through Monte Carlo simulation and convex optimization. Results show that increasing the share of spot trading enhances overall system efficiency, primarily because renewable energy has low marginal costs and high supply potential, thereby reducing average market prices and mitigating volatility. Simulations indicate that the optimal contract coverage rate may exceed the current policy lower bound, which would expand spot market space and promote renewable energy integration. Sensitivity analysis further reveals that fuel price fluctuations, renewable output, load structure, and risk preferences all affect the optimal proportion, though the overall conclusions remain robust. Policy implications suggest moderately relaxing the constraints on MLT contract proportions, improving contract design, and combining this with transmission expansion and demand response, in order to establish a more efficient and flexible market structure.
