Description
技术领域technical field

背景技术Background technique
随着微控制器和通信技术的快速发展，在电力用户侧实现需求侧响应已成为可能。而且采用分时电价政策可以调整电力用户用电习惯，因此，想要实现电力用户参与的削峰填谷，就要求电力用户主动参与削峰填谷。由于居民用户众多，用电时间比较分散，用户负荷近一半为弹性负荷，选择用电时间余量大。因此，居民用户的负荷非常适合参与需求侧响应。With the rapid development of microcontrollers and communication technologies, it has become possible to implement demand-side response on the power user side. Moreover, the time-of-use electricity price policy can adjust the power consumption habits of power users. Therefore, in order to realize peak-shaving and valley-filling with the participation of power users, power users are required to actively participate in peak-shaving and valley-filling. Due to the large number of residential users, the power consumption time is relatively scattered, and nearly half of the user load is elastic load, so there is a large margin for choosing power consumption time. Therefore, the load of residential users is very suitable for participation in demand side response.
但是，要求居民根据分时电价信息人工做出对家电运行时间的决策是不现实，若该决策由人工制定，则需要用户投入较大的工作量，无法实现，必须由家电智能控制系统根据居民意愿自动做出决策，并自动控制家电的运行。因此，设计适用于需求侧响应的智能家电控制系统具有重要的意义。However, it is unrealistic to require residents to manually make decisions on the running time of household appliances based on time-of-use electricity price information. Will makes decisions automatically and controls the operation of appliances automatically. Therefore, it is of great significance to design a smart home appliance control system suitable for demand-side response.
