Embodiment Construction

[0083] figure 1 It is a flow chart of the demand response control method for multi-energy complementary residential building of the present invention.

[0084] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Specifically include the following steps:

[0085] Step 1: According to the purpose of demand response control, determine the reference power load, distance function and weight of the objective function in turn. In this embodiment, the selected control purpose of the residential building is the maximum reduction of the demand response time, the demand response time is 19:00-21:00, and the reference power load of the objective function is selected as Y=(y 1 ,y 2 ,...,y n )=(0, 0, ..., 0), the distance function uses Euclidean distance The weight can be expressed as:

Abstract

The invention relates to a demand response control method for multi-energy complementation of a residential building. The method comprises the steps of selecting corresponding weights and reference loads according to different types of control targets of the residential building, such as the maximum economy, the maximum reduction of a peak value, and finally achieving the control of demand response through the optimization of a unified objective function. Compared with a traditional demand response control strategy method, a unified optimization objective function is adopted, and the universality of the demand response control method can be improved.

Description

technical field [0001] The invention relates to the technical field of demand response, in particular to a demand response control method for multi-energy complementary residential buildings. Background technique [0002] In recent years, with the continuous advancement of domestic industrialization and urbanization, the imbalance between the supply side and the demand side of the power grid has become more and more serious. According to statistics, my country's installed power generation capacity reached 1.9 billion kW in 2018, ranking first in the world. However, the average utilization hours of power generation equipment nationwide in 2017 was only 3,670 hours, which means that more than half of the power plants in the year were not fully utilized. In addition, the widespread application of renewable energy has further exacerbated the imbalance between the supply side and the demand side. [0003] Demand response (Demand Response, DR) alleviates the imbalance between pow...
