論文概要:The integration of renewable energy into modern power systems presents significant opportunities for reducing carbon emissions and enhancing energy sustainability. However, it also introduces challenges related to grid stability, demand-supply balancing, and efficient energy dispatch. This study investigates the optimization of power supply systems with high renewable energy penetration, incorporating both supply-side and demand-side resources. The research emphasizes the role of demand-side management (DSM), virtual power plants (VPP), and advanced storage technologies in addressing these challenges.
The methodology combines modeling and simulation approaches to evaluate the impacts of variable renewable energy (VRE) integration on grid operations. Case studies, including a feasibility analysis of a VPP in Chongming Island and a performance assessment of distributed energy systems in residential sectors, illustrate practical applications. Results indicate that coordinated DSM strategies, such as dynamic pricing and load shifting, enhance grid flexibility, reduce peak demand, and optimize energy utilization. Additionally, integrated renewable-storage systems, such as PV-pumped hydro storage (PHS), demonstrate the potential to improve renewable energy utilization and reduce overall generation costs.
The findings underscore the need for innovative market mechanisms and supportive policies to incentivize renewable energy adoption and DSM technologies. By integrating renewable energy systems with demand-side resources and advanced storage solutions, this research provides actionable insights for achieving a low-carbon, resilient energy infrastructure. The conclusions offer valuable guidance for policymakers, energy planners, and industry stakeholders in transitioning toward sustainable and efficient power systems.
