2 results about "Demand side" patented technology

This invention discloses a method and system for coordinated control of aggregated load on the demand side. The method includes: acquiring user-side electricity price, market electricity price fluctuations, and user baseline load forecast data; analyzing these to obtain a demand response target; based on the demand response target and combined with user characteristics, selecting corresponding price-based and incentive-based demand response modes, and constructing corresponding demand-side aggregated load models; wherein, based on the price-based demand response mode, a price-based demand-side resource aggregated load model is constructed; based on the incentive-based demand response mode, an incentive-based demand-side aggregated load model is constructed; according to the demand response mode and the demand-side aggregated load model, a control strategy for the aggregated load is determined, including adjustment, control, and hybrid strategies; the control strategies are classified according to applicable scenarios to obtain a classification result. This method can improve the renewable energy absorption capacity, reduce system operating costs, and improve the economic efficiency of system operation.

The invention relates to the technical field of power grid regulation and control evaluation, in particular to a multi-emerging main body aggregation participation system regulation potential quantitative evaluation method. The method comprises the following steps: constructing a time factor evaluation sub-model, a price factor evaluation sub-model and a physical factor evaluation sub-model through three dimension factors of a time factor, a price factor and a physical factor, wherein the time factor evaluation sub-model is constructed by adopting the characteristic that the regulation potential of an emerging subject is attenuated along with the approaching of transaction time; the price factor evaluation sub-model is constructed for a price response function; the physical factor evaluation sub-model determines the weight of each physical parameter by adopting a subjective and objective comprehensive evaluation method, and performs comprehensive sorting construction by utilizing a grey relational analysis method; three dimension factors are aggregated to establish a demand side resource aggregation model with market revenue maximization as a target, and multi-emerging subject aggregation participates in quantitative evaluation of system regulation potential. According to the invention, the accuracy and comprehensiveness of the evaluation result can be effectively improved.
