Regional power grid new energy acceptance and consumption capacity calculation method and system

Abstract

The invention provides a regional power grid new energy acceptance and consumption capacity calculation method and system. The method comprises the steps of calculating regional power grid new energyacceptance and consumption capacity considering peak regulation completion according to a power grid operating mode; enabling the new energy access capacity which is not greater than the regional power grid new energy acceptance and consumption capacity into each sub region power grid of the regional power grid; and when the new energy access capacity in each sub region power grid satisfies safetyand stability requirement, determining the regional power grid new energy acceptance and consumption capacity according to the new energy access capacity in each sub region power grid. By virtue of the method and the system, the main factors for limiting the new energy acceptance, such as constraint of peak regulation, constraint of safety and stability and the like, are taken into comprehensiveconsideration, so that reference and basis are provided for power grid dispatching operation and related policies issuing by the government.

Description

technical field [0001] The invention belongs to the field of electric power technology, and in particular relates to a method and system for calculating the new energy consumption capacity of a regional power grid. Background technique [0002] Different from conventional energy, new energy output has the characteristics of intermittent, fluctuating, and poor predictability. After large-scale new energy is connected to the grid, the randomness and volatility of its output will have multiple impacts on the power grid. The difficulty of new energy consumption is more prominent, and system peak regulation is an important aspect that needs to be considered. The work of new energy consumption has become the focus of attention of all parties in the society. [0003] Accurate calculation of new energy consumption capacity is an effective way to improve the level of new energy consumption. At present, most of the research on new energy consumption capacity is carried out from the ...
