Research on Load Demand Response Decision Considering Resource Correlation and Uncertainty

doi:10.3969/j.issn.1000-7229.2019.06.015

Abstract

Abstract: The demand response（DR）has certain uncertainty. In order to truly reflect the response of each uncertain user， this paper considers the correlation between spatial and temporal responsiveness of uncertain user resources represented by air conditioning. Firstly， the improved Latin hypercube sampling method is used to scale and correlate the responsivity， and the samples reflecting the response correlation are obtained. Secondly， the deterministic resources are introduced to establish the optimal decision model of the load aggregator（LA）， and the decision-making scheme is solved by the algorithm when the profit is the highest through random simulation and intelligence. Finally， an example is given to analyze the influence of the distribution parameters of deterministic resources， correlation and responsiveness on decision-making schemes and profits. Measures that can increase the profit include ordering deterministic resources， signing negative related uncertain users， increasing the average of responsiveness， reducing the variance of responsiveness.

Key words: demand response（DR）, correlation, uncertainty, Latin hypercube sampling, load aggregator（LA）
