In large power grid, the gradual phase-out of directly dispatched fossil fuel units will create a gap in regulation resources. In the short term, it will be difficult to find a large number of low-cost, clean, and controllable power sources to fill this gap, posing increasingly severe challenges to the safe and stable operation of both large-scale and urban power grids. To address this issue, it is urgent to explore and develop the vast adjustable resources on the load side within urban power grids and to rethink the operational approach of urban power grids. Therefore, this session will discuss technologies for exploring load-side resources in new urban power grids, evaluating their adjustability, situational awareness, power balance scheduling, energy balance scheduling, and intelligent control. Addressing the challenges of the new power system by fully dispatching internal resources within the new urban power grid.
The excessive use of fossil energy driven by socio-economic development has resulted in massive carbon dioxide emissions, leading to an increasingly severe greenhouse effect. Carbon emissions from the power system account for approximately 46% of the total carbon emissions in society. Therefore, building a new power system dominated by renewable energy to reduce carbon emissions is a crucial measure to address energy and environmental issues. Due to weather influences, renewable energy generation exhibits strong volatility, uncertainty, and long-cycle intermittency, leading to significant changes in power system operation and an increasing demand for dispatchable capacity. On the other hand, in the new power system, directly dispatched fossil fuel units with strong regulation capability will gradually phase out, while the dispatchable capacity on the grid side is limited. Currently, energy storage costs are high, making it necessary to explore load-side adjustable resources to compensate for the lack of system regulation capacity. Load-side adjustable resources are primarily concentrated in urban power grids, with the current participation of these resources in grid operations accounting for less than 4% of the maximum load. Effectively exploring and integrating these adjustable resources to enhance the dispatchable capacity of urban power grids is key to ensuring the stable operation of the new power system.
The proposed paper topics for this session are as follows:
