Embodiment Construction

[0069] like figure 1 As shown, a load operation optimization method considering flexibility potential includes the following steps:

[0070] 1. Establish a mathematical model of adjustable load.

[0071] The expressions of the mathematical models of air conditioners, electric water heaters, and washing machines are as follows:

[0072] 1) Air conditioning system: The air conditioning system adjusts the indoor temperature according to the deviation between the indoor temperature and the adjusted temperature.

[0073]

[0074] Among them, T in (t) is the indoor temperature at time t; T out (t+1) is the outdoor temperature at time t+1; η is the energy efficiency ratio of the air conditioner; P AC (t) is the output power of the air conditioner at time t; R is the equivalent resistance of the air conditioner; C is the equivalent capacitance of the air conditioner; Δt is the time interval.

[0075] 2) Electric water heater: The temperature of the hot water of the electric wa...

Abstract

The invention discloses a load operation optimization method considering flexibility potential. The method comprises the following steps (1) of establishing a mathematical model capable of regulatingand controlling a load; (2) establishing a load optimization model based on a flexibility potential; and (3) obtaining the optimal operation time period of each load. In the step 1), a mathematical model capable of regulating and controlling loads is established for various loads; in the step 2), a load optimization model based on the flexibility potential is established, and the load optimizationmodel aims to reduce power consumption cost of a user to the minimum. The method is advantaged in that an objective of the invention is to solve technical problems in the prior art that the considered load type is single, the applicable scene has relatively large limitation, and the flexibility potential of the demand side needs to be further improved.

Description

technical field [0001] The invention belongs to the technical field of electric power systems, and in particular relates to an optimization method for load operation, in particular to a load operation optimization method that considers the flexibility potential of various loads. Background technique [0002] With the continuous expansion of the scale of the microgrid, people pay more and more attention to the power demand response. As an important resource of load demand response, the load with flexibility potential is of great significance to improve the safe and stable operation level of the power grid. Because there are a large number of adjustable loads in the microgrid, and there are many types of adjustable loads, which affect the stable operation of the microgrid. Therefore, optimizing the load demand is the current research focus. [0003] In prior art literature: Development of a data driven approach to explore the energy flexibility potential of building clusters...
