Embodiment Construction

[0037] The control objects of the algorithm of the present invention are high-power household appliances and distributed power sources for residential users, including electric water heaters, air conditioners, electric vehicles, photovoltaic power generation devices, and the like. Before executing the algorithm, the user first sets the comfort range of all the controlled appliances. For example, for a water heater, the optimum water temperature is 40°C-50°C; for an air conditioner, the room temperature can be set at 22°C-26°C; for an electric vehicle, set the battery SOC min 40%, SOC min 95%.

[0038] Further, the intelligent control algorithm of the new home energy management system, the work of each household appliance and the HEM control situation, the comfort level exceeding the limit index and the dynamic priority are as follows:

[0039] (1) Electric water heater: set the maximum water temperature T WH,s ; When the water temperature is higher than the maximum temperat...

Abstract

The invention discloses a novel household energy management system intelligent control algorithm. The algorithm mainly aims at high-power household appliance loads among resident users to perform DR control, and energy supplying modes of a household distribution type power supply are selected. Setting of comfort range of the household appliances is fully considered for the users. A concept of comfort limit index is put forward according to the current working state of the household appliances, and dynamic priority of all the household appliances is calculated on the basis of the concept and a control decision is executed according to the priority so that full automation in control is realized and initiative of the users in participating DR is enhanced.

Description

technical field [0001] The invention relates to an intelligent control algorithm for a household energy management system, and belongs to the technical field of new energy power generation and 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. Although this method can meet the electricity demand during peak hours, a large number of backups are idle during off-peak hours, which greatly reduces the efficiency of generators and causes waste of resources. At the same time, the emergence of the energy crisis has led to a sharp rise in the price of fossil fuels. Western countries have launched explorations and practices to solve the contradiction between power supply and demand by reducing demand-side loads, and the concept of demand response (DR) ...
