Description

一种家庭能量管理系统 A home energy management system

技术领域 FIELD

[0001] 本发明涉及一种管理系统,具体是一种家庭能量管理系统。 [0001] The present invention relates to a management system, in particular a home energy management system.

背景技术 Background technique

[0002] 为满足用电需求,早期的电力部门一般根据预测的用电负荷,来确定发电容量,以使发电能力满足需求水平。 [0002] To meet the demand for electricity, the power sector early prediction is generally based on the power load, the power generation capacity is determined so that the generating capacity to meet demand levels. 这种做法虽然可以保证高峰时段的用电需要,但却使一些发电容量在高峰负荷以外的其它时段处于闲置状态。 Although such an approach ensures that the peak electricity demand periods, the power generation capacity so that some but other periods than the peak load is idle. 20世纪70年代左右,石油危机导致了能源价格大幅上涨,西方国家不再一味追求以装机容量来满足需求的做法,展开了通过削减需求侧负荷来解决电力供需矛盾的探索与实践,需求侧响应(demand response, DR)的理念随之诞生。 Around the 1970s, the oil crisis led to a sharp rise in energy prices, the West no longer blindly pursue the capacity to meet the needs of the practice, started exploration and practice to solve the power shortage of demand by reducing the load side, demand side response (demand response, DR) concept born.

[0003] 根据激励方式的不同,DR可分为价格型和激励机制型两大类。 [0003] Depending on the mode of excitation, DR type and price can be divided into two categories incentives. 在高峰负荷期间,起决定作用的DR类型包括紧急需求响应、可中断负荷、直接负荷控制及容量响应四种。 During peak load, play a decisive role DR types include urgent demand response, interruptible load, and direct load control volume responsiveness four. 这四种都属于激励型DR,通过用户接收相关控制信号作出响应,而非通过电价实施DR。 These four are all excitation type DR, associated control signals received by the user in response, not by electricity embodiment DR. 目前,大部分激励型DR控制的研究都是围绕一些大电力用户,如工业及商业用户等,而针对居民用户研究较少。 At present, most of the incentive-based DR control revolves around a number of large electricity users, such as industrial and commercial users, etc., and less for the residents of user research. 随着经济的发展及居民消费水平的提高,居民耗电量的增长速率也越来也大。 With the improvement of the level of economic development and consumption of households, their electricity consumption growth rate is also increasingly large. 因此,有必要针对居民用电,展开相关DR控制方面的研究。 Therefore, it is necessary for residential electricity, research related to control of DR unfold. 美国的AH Mohsenian等人提出了针对小功率家电开展DR响应,但其研究对总体家电功耗并无太大影响。 American AH Mohsenian, who proposed to carry out small-power appliances for the DR response, but the research is not much impact on the overall power consumption of appliances.

[0004] 此外,智能电网的发展也可以解决精确供能、电力需求侧管理、电网自由接入、多电源互动以及分散储能等问题,它不仅服务于大电网而且服务于电力终端用户。 [0004] In addition, the development of smart grid can solve the problem precise energy supply, demand side management, free access to the grid, and more interactive power and decentralized energy storage, which not only serves the large power grid and serve the end user. 因此,借助智能电网中的智能量测装置,可开发出一套针对大功率家电负荷的家庭能量管理系统,从而实现居民用户中需求侧管理的自动控制,而非电力公司通过拉闸限电来被动控制用电量,提高用户参与需求侧管理的积极性与主动性。 Thus, with smart grid intelligent measuring device, we can develop a home energy management system for the load of large appliances, in order to achieve automatic control side management of residential customers in demand, rather than by the power company to power cuts passive control electricity consumption, improve user enthusiasm and initiative to participate in demand-side management.
