Abstract

Provided is a user side load response method based on adjustment and control on temperature of load clusters. The user side load response method includes: performing thermodynamic modeling on a temperature control load to obtain a temperature control model in direct load control; constructing a mapping quantity to describe the change state of a temperature control load relay switch; obtaining adjustable capacity of the temperature control load through the mapping quantity; introducing temperature control load clusters to solve the problem that control precision cannot satisfy condition requirements; and finally calculating the influence of each load cluster in different load cluster control schemes on comfort degree.

First claim

What is claimed is:

1. A user side load response method based on adjustment and control on temperature of load clusters, comprising:
receiving, by a load aggregator, a dispatching command sent from a dispatching center at a time point t, wherein the dispatching command is an expected dispatchable capacity D f (t) at the time point t;
performing calculation, by the load aggregator, to obtain an actual dispatchable capacity D(t) of a temperature control load at the time point t;
obtaining a controlled temperature setting value θ ref of the temperature control load corresponding to the expected dispatchable capacity D ref (t), and obtaining a to-be-controlled temperature value θ t − of the temperature control load corresponding to the actual dispatchable capacity D(t);
calculating, by the load aggregator, a temperature change quantity u(t) of the temperature control load at the time point t through θ ref −θ t − ;
dividing, by the load aggregator, a temperature control load group that participates in adjustment and control into a plurality of temperature control load clusters, and performing calculation to obtain a temperature change quantity u i (t) of each of the plurality of temperature control load clusters according to the temperature change quantity u(t);
sending, by the load aggregator, temperature change quantity u i (t) of each of the plurality of temperature control load clusters, to temperature control loads in the each of the plurality of temperature control load clusters,
receiving, by the temperature control loads in the each of the plurality of temperature control load clusters, the temperature change quantity u i (t) of each of the plurality of temperature control load clusters, and
adjusting, by the temperature control loads in the each of the plurality of temperature control load clusters, actual dispatchable capacities D(t) of the temperature control loads in the each of the plurality of temperature control load clusters according to the temperature change quantity u i (t) of each of the plurality of temperature control load clusters,
wherein the temperature control load group comprises a plurality of temperature control loads,
wherein the dividing, by the load aggregator, the temperature control load group that participates in adjustment and control into the plurality of temperature control load clusters comprises:
dividing the temperature control load group into the plurality of temperature control load clusters according to types of temperature control loads.

2. The user side load response method according to claim 1 , wherein performing calculation, by the load aggregator, to obtain a temperature change quantity u i (t) of each of the plurality of temperature control load clusters according to the temperature change quantity u(t) comprises:
