Abstract

This paper introduces an optimal hierarchical load dispatch method based on thermal-power characteristics. Firstly, the thermal transmission model is applied to optimize the average load of air conditioning units. This characteristic is linearized to suit hourly planning. Next, leveraging the features of the air conditioning temperature difference-power model, a grouping method for air conditioning units is proposed based on auxiliary load aggregates. The optimal hierarchical model is constructed using intermediate variables, demonstrating that the Nash equilibrium solution is the unique strategy to optimize the hierarchical structure in the non-cooperative game. In the field of electrical engineering: The calculation results and simulations indicate that the optimized method of load distribution for air conditioning based on thermal-power characteristics can minimize the adverse impact of peak auxiliary loads on the power grid.
