Quantitative evaluation method of user-side resource adaptability for power grid different regulation demands

Abstract

At present, the full utilization of decentralized resources at the bottom user-side in the power system has become one of the important means of energy transformation and utilization and promoting the sustainable development of economy and society. However, the user-side resources have the characteristics of large quantity, different types, serious parameter differentiation, operation laws and regulation characteristics. After large-scale access, there are problems of effective perception and accurate aggregation in participating in power grid regulation. The existing direct acquisition and direct control model based on single equipment is difficult to adapt to the multi-form load aggregation under the demand of multiple power grid regulation. The quantitative evaluation method of user-side resource aggregation adaptability for different power grid regulation requirements constructs the evaluation systems of 5 primary indicators, 11 secondary indicators and 34 tertiary indicators respectively, which is conducive to guiding the resource aggregation under the requirements of power grid regulation for different granularity resource aggregation, response time and duration, It realizes the adaptive quantitative evaluation of indicators under different regulation needs, and fully excavates the regulation potential of user-side adjustable resources, which has a certain engineering application prospect.
