Description

technical field [0001] The invention belongs to the technical field of power grid energy saving and loss reduction, and in particular relates to a comprehensive evaluation method for electric power energy saving of a charge-source combined peak-shaving scheme. Background technique [0002] With the rapid development of centralized access capacity of large-scale wind power bases, large-scale long-distance transmission and its randomness and volatility characteristics have caused a significant increase in network losses through the power grid. Incorporating high-energy loads with adjustable and interruptible characteristics into the peak-shaving control system to achieve coordinated control of load sources can achieve the dual goals of power saving and on-site consumption of new energy. [0003] However, the energy saving of load-source combined peak-shaving power with high-energy loads involves three aspects: power grid, power supply, and high-energy loads. It involves a wide...
