The invention provides a method and a device for predicting the peak load regulation capacity of a power network, which can realize the quantitative prediction of the peak load regulation capacity of the power network.

Description

technical field [0001] The invention belongs to the field of electric power science and technology, and more specifically relates to a method and device for predicting peak-shaving capability of a power grid. Background technique [0002] In recent years, with the development of urbanization and central heating business, the proportion of combined heat and power units in the power grid has been increasing. Since the operation mode of combined heat and power units is determined by heat, during the heating period in winter, the power grid has a large peak load. How to scientifically and reasonably predict the adjustable load of the power grid and improve the peak-shaving capability of the power grid has become a common concern of power grid enterprises and dispatching departments. [0003] When the power grid dispatching department conducts power distribution and load dispatching, the cogeneration unit operates in a heat-fixed power mode, which restricts the flexibility and di...
