Constant Frequency Air Conditioning Load Aggregated Modeling and Its Power Tracking Strategy Considering Heterogeneity
摘要
Abstract
To simplify the aggregated model for air conditioning loads, uniform parameters are usually assumed in recent research. However, the actual situation that the parameters of controlled air-conditioning group are significantly various, and the influence of the minimum outage time and integer setting temperature are neglected. This paper proposes an improved aggregated modeling method considering the heterogeneity of air conditioning loads, which improves the power simulation precision of the controlled group through grouping air conditioners by rated refrigeration capacity and using fuzzy C-means clustering algorithm. By introducing the minimum outage time and setting temperature adjustment with integer constraints, the simulation scenarios became closer to the actual operation condition of constant frequency air conditioning. Besides, in the actual calculation, the sparse matrix was stored in the coordinate format to improve the calculation speed and practicability of the model. Based on the improved aggregated model, a power tracking strategy is proposed consequently, which calculates the demand response capacity of each cluster at each time step, and optimizes the regulating objects by solving the 0-1 integer programming problem. The simulation results verify the effectiveness of the proposed strategy in power tracking.关键词
