基于融合通信的多用户用电自平衡系统和方法Multi-user power self-balancing system and method based on converged communication

技术领域technical field

本发明涉及智能用电和融合通信技术领域，特别是指一种基于融合通信的多用户用电自平衡系统和方法。The present invention relates to the technical field of intelligent power consumption and fusion communication, in particular to a self-balancing system and method for multi-user power consumption based on fusion communication.

背景技术Background technique

随着社会的快速发展以及电能替代的大力推广，家庭用户的用电量飞快的增长，其在总的用电负荷中所占的比例也越来越大。而随着通信技术的发展，尤其是融合通信的快速发展，其在家庭用电控制方面的应用推广，在技术上已经能够实现对于家庭用电负荷的优化调节。With the rapid development of society and the vigorous promotion of electric energy substitution, the electricity consumption of household users is increasing rapidly, and its proportion in the total electricity load is also increasing. With the development of communication technology, especially the rapid development of converged communication, its application and promotion in household power consumption control has been able to realize the optimal adjustment of household power consumption technically.

不同于工业用户，家庭用户具有多样性的特点，从而其用电情况也呈现多样化。某些家庭的用电负荷高峰可能是另外一些家庭的用电负荷的低谷期，这也为各个不同的家庭对于需求响应调节的合作成为了可能。Different from industrial users, household users have the characteristics of diversity, so their electricity consumption is also diversified. The peak electricity load of some households may be the trough period of other households' electricity load, which also makes it possible for different households to cooperate in demand response regulation.

现在现有的各个需求响应的模型考虑的都是单个用户与电力公司之间的互动关系。一般来说，现有的需求响应调节大都是电力公司通过分时电价或其它激励措施引导居民的用电行为或与智能用电的家庭签订需求响应的合同，在不同的符合条件下各个用户根据合同约定的电量进行负荷的调节。而作为用户来说，一旦与电力公司签订了需求响应合同，在电力高峰时只能通过削减负荷来完成响应，对自己的用电舒适度造成了较大的影响，同时大大增加了用户违约超负荷用电的可能。同时，在某些时段，用户的负荷量又远远小于与电力公司合同约定的负荷量，造成某些负荷浪费。The existing demand response models consider the interaction between a single user and the power company. Generally speaking, most of the existing demand response adjustments are power companies guiding residents’ electricity consumption behavior through time-of-use electricity prices or other incentives, or signing demand response contracts with households that use smart electricity. The electricity agreed in the contract is used for load regulation. As a user, once the demand response contract is signed with the power company, the response can only be completed by cutting the load during the peak power period, which has a great impact on the comfort of their own electricity consumption, and at the same time greatly increases the user's breach of contract. The possibility of load electricity. At the same time, in certain periods of time, the user's load is far less than the load agreed in the contract with the power company, resulting in some load waste.

另一方面，本发明实施例还提供了一种基于融合通信的多用户用电自平衡方法，该方法应用于如上述实施例所述的基于融合通信的多用户用电自平衡系统。On the other hand, the embodiment of the present invention also provides a multi-user power self-balancing method based on converged communication, which is applied to the multi-user power self-balance system based on converged communication described in the above embodiments.

具体的，所述基于融合通信的多用户用电自平衡方法，包括以下步骤：Specifically, the multi-user power self-balancing method based on converged communication includes the following steps:

家庭用户终端实时监测家庭的总负荷量，并以预设时间间隔向组控制终端上报当前的总负荷量和可用于置换的负荷量；The home user terminal monitors the total load of the family in real time, and reports the current total load and the load available for replacement to the group control terminal at preset time intervals;

当所述家庭用户终端监测到总负荷量大于预设的负荷量上限时，向所述组控制终端发送置换申请；When the home user terminal detects that the total load is greater than a preset load upper limit, send a replacement application to the group control terminal;

所述组控制终端根据所述置换申请，在用电组内寻找确定可匹配置换家庭，并向所述可匹配置换家庭的家庭用户终端发送置换请求；According to the replacement application, the group control terminal searches for and determines a family that can be matched and replaced in the power consumption group, and sends a replacement request to the user terminal of the family that can be matched and replaced;

所述组控制终端接收所述可匹配置换家庭的家庭用户终端返回的反馈消息，若所述反馈消息为确认，则将两个家庭的负荷量置换并通过该两个家庭各自的家庭用户终端重新设定负荷量上限；若所述反馈消息为拒绝，则继续寻找可匹配置换家庭。The group control terminal receives the feedback message returned by the family user terminal that can be matched with the replacement family, and if the feedback message is confirmed, replaces the loads of the two families and resets the load through the respective family user terminals of the two families. Set the upper limit of the load; if the feedback message is rejection, continue to search for a matching replacement family.

参考图2，为本发明实施例的基于融合通信的多用户用电自平衡方法流程图。作为一个具体的实施例，所述方法包括以下步骤：Referring to FIG. 2 , it is a flowchart of a multi-user power self-balancing method based on converged communication according to an embodiment of the present invention. As a specific embodiment, the method includes the following steps:

步骤201、家庭用户终端实时监测各个家用电器的运行情况及家庭总负荷情况，每1分钟向组用户终端上传一次当前家庭负荷情况数据以及可用于置换的负荷量，可用于置换的负荷量等于家庭申报的当前时段负荷量上限减去用户当前实际负荷量再乘以用户自行设定的保留系数，其中，保留系数介于0到1之间。Step 201. The home user terminal monitors the operation status of each household appliance and the total household load in real time, and uploads the current household load status data and the load available for replacement to the group user terminal every 1 minute. The load available for replacement is equal to the household load. The declared upper limit of load in the current period minus the current actual load of the user is multiplied by the retention coefficient set by the user, wherein the retention coefficient is between 0 and 1.

步骤202、当家庭总负荷量超过申报的负荷量时，家庭控制终端向组控制终端传送负荷量置换请求以及请求置换的负荷量。请求置换的负荷量等于家庭当前实际总负荷量减去该家庭申报的当前时段的负荷量上限。Step 202, when the total household load exceeds the declared load, the home control terminal transmits a load replacement request and the requested load replacement to the group control terminal. The load requested to be replaced is equal to the current actual total load of the household minus the upper limit of load declared by the household for the current period.

步骤203、组控制终端收到置换请求后，自动在组内寻找可匹配置换的家庭，可匹配置换的家庭指其上传的可置换的负荷量大于请求置换家庭请求的置换负荷量。组控制终端向该可匹配置换家庭控制终端发送电量置换请求，并向相应的用户手机发送置换消息。Step 203: After receiving the replacement request, the group control terminal automatically searches for families in the group that can be matched and replaced. A family that can be matched and replaced means that the replaced load uploaded by it is greater than the replacement load requested by the family requesting replacement. The group control terminal sends a power replacement request to the matching replacement home control terminal, and sends a replacement message to the corresponding user's mobile phone.

步骤204、家庭用户终端收匹配请求，可根据用户设定，自动回复同意置换或拒绝置换，并向用户手机发送置换请求信息，用户可通过手机对于置换请求进行同意或否决操作。Step 204: After receiving the matching request, the home user terminal can automatically reply to agree or reject the replacement according to the user's settings, and send a replacement request message to the user's mobile phone. The user can approve or reject the replacement request through the mobile phone.

步骤205、如果组控制终端收到家庭控制终端同意置换的反馈后，向置换双方家庭控制终端发送置换成功的消息，并下达置换后各自的负荷上限。如果组控制终端收到家庭控制终端拒绝置换的反馈，自动寻找下一个可匹配目标，继续置换过程。如果所有置换失败，则向发出置换请求的家庭控制终端发出置换失败的消息。Step 205: If the group control terminal receives the feedback that the home control terminal agrees to the replacement, it sends a replacement success message to the home control terminals of both replacement parties, and issues their respective load upper limits after replacement. If the group control terminal receives the feedback that the family control terminal refuses to replace, it will automatically find the next matching target and continue the replacement process. If all replacements fail, a replacement failure message is sent to the home control terminal that sent the replacement request.

步骤206、如果家庭用户终端收到置换成功的消息，根据组用户终端下达的消息，自动将监测的负荷上限更改。如果家庭用户终端收到置换失败的消息，根据用户事先设定的家电使用优先级自动停用一部分家电，直至家庭总负荷小于申报的当前时刻的最大负荷量。Step 206, if the home user terminal receives the message that the replacement is successful, automatically change the monitored load upper limit according to the message sent by the group user terminal. If the home user terminal receives the message of replacement failure, it will automatically deactivate some of the home appliances according to the home appliance use priority set by the user until the total household load is less than the declared maximum load at the current moment.
