Embodiment Construction

[0028] The control object of the algorithm of the present invention is high-power household appliances for residential users, including electric water heaters, air conditioners, dryers, electric vehicles, etc., and the power consumption thereof is 2KW (air conditioners) to 3.3KW-9KW (electric vehicles). Before executing the algorithm, the priority and comfort range of all controlled loads should be set first, and the setting data are shown in Table 1.

[0029] Table 1 Controlled load priority and comfort range setting

[0030]

[0031] Among them, the priorities from high to low are: electric water heater-air conditioner-dryer-electric vehicle; for water heaters, the optimum water temperature is 43.33°C-48.89°C; for air conditioners, the room temperature can be set to 24.4°C (±2°C ); for the dryer, the work completion time, the maximum power-off time and the minimum power-on time (both refer to the heating part) can be set artificially; for the electric vehicle, the chargin...

Abstract

The invention discloses an intelligent control algorithm for a home energy managing (HEM) system. The algorithm is mainly used for achieving DR control on large-power power load in a residential user. The HEM system is applied to the residential user to automatically carry out demand response (DR) control on large-power household load. Before the algorithm is carried out, the user sets a range of the priority and the comfortableness of controlled load at first, then the HEM system receives power utilization limitation and DR time request signals from an electric power company, the control algorithm is carried out by comparing the actual power utilization amount of the user and the power utilization limitation, and a control decision is made to achieve DR automatic control. The algorithm fully takes the user comfortableness and the household appliance priority into consideration and meanwhile achieves full automation of house power utilization management.

Description

technical field [0001] The invention relates to an intelligent control algorithm, in particular to an intelligent control algorithm for a household energy management system, and belongs to the technical field of demand side response control. Background technique [0002] In order to achieve the balance of power supply and demand, the traditional method is that the power company determines the power generation capacity according to the forecasted power load, so as to meet the power demand level. This method can guarantee the power demand during peak hours, but during non-peak load periods, a large number of generators are idle, which greatly reduces the efficiency of the generators and causes a waste of resources. [0003] In the 1970s, with the emergence of the oil crisis, the price of primary energy rose sharply. Western countries began to explore and practice to solve the contradiction between power supply and demand by reducing the load on the demand side. The demand side...
