【摘要】：随着电力改革的逐步深入，打破垄断、引入良好的竞争机制、优化电网的资源配置、提高电力市场的运行效率成为我国电力改革的方向。一个发展良好的电力市场必不可少的是需求侧的电价反馈。微观经济学相关理论指出，当价格由供需两侧共同决定的时候，，市场的收益最大，因此未来电网引入需求响应机制是必然的。需求响应项目鼓励用户积极参与电网的管理，对需求响应信号做出积极的响应，从而实现维护电力系统稳定运行，解决用电高峰电力供应不足及用电低谷电力资源利用率过低的问题。那么普通的家庭用户，在实施的需求响应项目中应该如何更好地根据价格信号控制家庭负荷、管理好家庭能源，从而在减少能源消耗和电价花费的基础上更进一步的实现削峰填谷以及优化资源配置，这是未来电力市场能否成功的关键问题之一。首先，本文介绍了需求响应的概念、实施所需的技术条件与国家现有的相关政策。针对我国在某些省市对大工业用户已经实施的需求响应项目及国外现行较成熟的需求响应项目做了详细的研究分析。其次，结合已有的技术条件和需求响应项目实施情况，针对我国居民用户的家用电器负荷的使用习惯，提出分时电价需求响应项目。对参与该项目的家庭负荷进行分类分析，针对不同负荷的不同特点提出不同的控制目标函数。根据目标函数设计家庭能源管理优化算法，并对该算法进行可行性分析。最后，在MATLAB平台下，对不同的负荷控制目标函数，本文对家庭能源控制优化算法进行编程仿真验证。针对单用户目标、多用户目标、控制优化算法的多个约束条件以及实施的需求响应项目的价格高低等对家庭能源控制结果会产生影响的各种因素进行仿真分析。仿真结果显示本文提出的基于需求响应的控制策略可以达到控制家庭负荷用电、优化资源配置、削峰填谷、节约电费的效果。
[Abstract]:With the deepening of electric power reform, breaking monopoly, introducing good competition mechanism, optimizing the distribution of power grid resources and improving the operation efficiency of power market become the direction of electric power reform in our country. A well-developed electricity market is essential for demand-side price feedback. The related theories of microeconomics point out that when the price is determined by both sides of supply and demand, the market returns the most, so it is inevitable to introduce demand response mechanism into power grid in the future. The demand response project encourages users to take an active part in the management of the power grid and to respond positively to the demand response signals, so as to maintain the stable operation of the power system. To solve the problem of insufficient peak power supply and low utilization rate of power resources. Well, in the implementation of the demand response project, the average household user should better control the household load according to the price signal, and manage the household energy well. Therefore, on the basis of reducing energy consumption and electricity price cost, we can further realize peak cutting and valley filling and optimizing resource allocation, which is one of the key problems to be successful in the future electricity market. Firstly, the concept of demand response is introduced in this paper. Implement the necessary technical conditions and the existing relevant policies of the country. This paper makes a detailed research and analysis on the demand response projects that have been implemented by large industrial users in some provinces and cities of China and the mature demand response projects in foreign countries. Secondly, combining the existing technical conditions and the implementation situation of the demand response projects, According to the usage habit of household appliance load of our country's residents, the demand response item of timesharing electricity price is put forward. The household load involved in the project is classified and analyzed, and different control objective functions are put forward according to the different characteristics of different loads. According to the objective function, the optimization algorithm of household energy management is designed, and the feasibility of the algorithm is analyzed. Finally, under the MATLAB platform, for different load control objective functions, the optimization algorithm of home energy control is verified by programming simulation. Aiming at single user target, multi-user goal, multiple constraints of control optimization algorithm and the price of implementing demand response project, this paper makes simulation and analysis on various factors that will affect the result of household energy control. The simulation results show that the proposed control strategy based on demand response can achieve the effect of controlling household load, optimizing resource allocation, cutting peak and filling valley, and saving electricity cost.
