What is Source-Grid-Load-Storage Integration?
Source-Grid-Load-Storage Integration is a comprehensive framework designed to unify various components of the energy landscape, including power sources, the grid, energy loads, and storage systems. The primary goal of this integration is to enhance the efficiency and reliability of the power system, while optimizing energy utilization and balancing supply with demand.
Key Components:
Source: This encompasses a variety of energy generation methods, such as thermal, hydropower, nuclear, wind, solar, and biomass.
Grid: This refers to the intricate network of substations, power lines, and distribution stations responsible for delivering electricity.
Load: Represents the total energy consumption by electrical devices within a given area.
Storage: Involves energy storage systems that retain excess power for release during peak demand, functioning effectively as a large “power bank.”
Historically, power grids operated under a “source-follow-load” model, leading to imbalances that could compromise system stability. In contrast, the future landscape is expected to embrace interconnected grids and microgrids, fostering a more dynamic and resilient energy environment.
Implementation Models
Efficient Source-Grid-Load-Storage Integration employs load-side adjustments and establishes engagement pathways for market participation across three distinct levels:
Regional (Provincial) Level: Facilitates open markets for power generation and load adjustments, enabling flexible responses driven by price signals.
Municipal (County) Level: Focuses on developing local grid projects that integrate renewable energy sources and enhance infrastructure to address urban energy demands.
Park (Residential Area) Level: Encourages the use of innovative technologies and new business models to promote distributed energy generation and storage solutions.
Business Models for Participants
The successful implementation of Source-Grid-Load-Storage Integration involves several key participants, each deriving unique benefits:
Clean Energy Generation: Emphasizes multi-type energy transactions to maximize power utilization.
Thermal Power Producers: Gains enhanced flexibility that allows for increased adjustment functions and ancillary service revenues.
Grid Enterprises: Optimizes the aggregation of resources to boost renewable energy consumption and sales.
Electricity Retailers: Engages in load analysis to create interaction plans and earn commission-based rewards.
Interruptible Loads: Offers auxiliary services and partakes in direct transactions to reduce costs and improve system performance.
Distributed Energy Storage Companies: Benefits from peak-valley price differences, market trading, demand-side responses, and energy management services.
Conclusion
As the renewable energy landscape continues to evolve, Source-Grid-Load-Storage Integration will play a pivotal role in achieving “dual carbon” goals (carbon peak and carbon neutrality) and promoting a sustainable energy future. By integrating diverse energy sources, enhancing grid efficiency, and optimizing energy consumption, this innovative framework stands at the forefront of advancing modern energy systems.
Embracing Source-Grid-Load-Storage Integration today is essential for stakeholders across the energy sector looking to adapt to a rapidly changing environment and contribute to a greener, more sustainable world.
