Household Load Control Based On Demand-side Response

With the rapid development of the national economy,the national electricity consumption for production and living has also increased significantly,and the demand for electricity in various regions has far exceeded the annual growth rate of power generation.With the increasing shortage of fossil energy,the problem of environmental pollution is becoming more and more serious,and the consumption capacity of new energy is still relatively low,which is far from meeting the growing demand for electricity.At this time,it is difficult to meet the increased load demand only by increasing the capacity of the generator set on the grid supply side.However,if the load can be directly controlled from the demand side,this can reduce the load pressure of the power grid to a certain extent,which is conducive to the balance and stability of the power grid.This article first summarizes the content and research significance of demand-side response,and analyzes the necessity of resident users to participate in demand-side response.Then specifically introduces the definition and classification of demand-side response,analyzes the ability of resident users ’household load to participate in demand side response load scheduling,classifies household load according to this,and analyzes the energy storage air conditioner in the interruptible load as an example.The effect of resident users participating in the demand-side response is verified.For uninterruptible loads,this paper constructs a load optimization scheduling model that comprehensively considers economy and residents’ life comfort,and then introduces inconvenient cost coefficients.The model is solved using the Yalmip toolbox and the SCIP solver in OPTI toolbox.Different cost coefficients are calculated to verify the correctness and effectiveness of the model.Finally,this paper introduces thermal comfort PMV to construct a multi-region aggregation model for temperature-controlled load participation in power market transactions,analyzes the curable potential of temperature-controlled load participation in power load scheduling,and constructs a two-layer model for temperature-controlled load participation in power market transactions And verified the feasibility of the proposed model through simulation.The purpose of this study is that resident users participate in demand-side response.While satisfying the residents’ comfort level,by changing their own electricity consumption habits,they respond to the power company’s real-time electricity price plan and related incentive policies,thereby reducing electricity costs.Reduce the peak load of the power grid to achieve the goal of win-win for users,power grid and society.
