Temperature control load hierarchical aggregation control method for intelligent building

Abstract

The invention provides a temperature control load hierarchical aggregation control method for an intelligent building. The method comprises the following steps: 1, constructing the hierarchical control architecture of heterogeneous temperature control load clusters which are aggregated and distributed dispersedly by taking a building as a unit; in an upper-layer control architecture,determining the scheduling capacity which should be provided by each building through distributed containment control based on the aggregation characteristics of the heterogeneous temperature control loads dispersedly distributed in different buildings by means of a load aggregator according to the scheduling requirement of the power distribution network system and the scheduling capacity level which can be provided by each building; sending a scheduling control requirement which contains the scheduling capacity provided by each building to a building controller in a lower-layer control architecture; and inthe lower-layer control architecture, according to the scheduling control requirement sent by the load aggregator, adjusting the running state of a controlled temperature control load in the same building through a conversion time matching control strategy by means of a building controller. According to the invention, the coordination control of load scheduling capacities provided by different buildings in the sparse communication network is realized.

Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to a temperature-controlled load hierarchical aggregation control method for smart buildings under the smart grid demand response mechanism. Background technique [0002] In the context of energy structure transformation, the current massive integration of renewable energy represented by wind power and photovoltaics into the modern power system is in an unprecedented period of rapid development. Unlike traditional power generation units, renewable energy is restricted by natural factors, and its output presents In addition, renewable energy such as wind power and photovoltaics do not use synchronous generators for power generation, and the increase in renewable energy power generation cannot increase the inertia of the system like traditional power generation units. As the penetration rate of renewable energy increases, the proportion of synchronous generators in operation decre...
