The invention discloses an optimized scheduling method with a controllable air conditioning load. The method comprises the steps of: establishing an air conditioning load group aggregation model; using a Kalman filter algorithm to estimate the state of the air conditioning load group; establishing an optimal scheduling model of a controllable air conditioning load aggregation group; and employingthe CPLEX to solve the optimal scheduling model of the controllable air conditioning load aggregation group. The optimal scheduling method with the controllable air conditioning load can overcome theproblems of the unreasonable load control method influencing the safe and stable operation of the power system in the prior art, guarantees that distribution of the air conditioning load group betweenthe upper and lower limits of the temperature is unchanged after control and keeps the diversity of air conditioning load groups.
Description
technical field [0001] The invention relates to the technical field of electric loads, in particular, to a research on an optimal scheduling method for controllable air-conditioning loads. Background technique [0002] There are a large number of loads with energy storage characteristics in the power system. Short-term switching or changing control parameters of such loads will not have obvious negative effects on users' electricity consumption, and have the potential to actively participate in system power balance control. The air-conditioning load is a typical representative load. Directly adjusting the operating state of the air-conditioning load is conducive to fully tapping the controllable resources on the load side, coordinating with the resources on the power generation side, and realizing active power balance control economically, efficiently and safely. [0003] Utilizing the controllable air-conditioning load to actively participate in the active power balance con...
