Direct Load Control Model and Simulation for Clean Energy Accommodation in Distribution Network
摘要
Abstract
The paper studied the direct load control technology and proposed a novel load power control method by changing the set point temperature in the thermodynamic controllable loads. The thermodynamics controllable loads transmission dynamic model was established based on a set of two coupled partial differential equations, and then it was approximated to the control oriented finite-dimensional state space model using the finite difference method. The power tracking sliding mode variable structure control (SMVSC) strategy was proposed which can deal with the uncertainties of variable power generation, and its convergence was verified by Lyapunov stability theory. Taking a small distribution network, as an example, 1000 cooling air conditioning loads were simulated and power tracking error analysis showed that wind power could effectively track the wind power accommodation target, and the set point temperature control analysis results showed that the proposed method was accepted by more than 90% users. The method paved the path for the demand-side response load in clean energy Accommodation applications.关键词
