基于可控负荷的智能电网电压频率多目标优化控制
Multi-objective optimization for voltage and frequency control of smart grids based on controllable loads
摘要
Abstract
The output uncertainty of high-proportion distributed power generation severely affects the system voltage and frequency. Simultaneously, controllable loads have also annually increased, which markedly improve the capability for nodal-power control. To maintain the system frequency and voltage magnitude around rated values, a new multi-objective optimization model for both voltage and frequency control is proposed. Moreover, a great similarity between the multi-objective optimization and game problems appears. To reduce the strong subjectivity of the traditional methods, the idea and method of the game theory are introduced into the solution. According to the present situational data and analysis of the voltage and frequency sensitivities to nodal-power variations, the design variables involved in the voltage and frequency control are classified into two strategy spaces for players using hierarchical clustering. Finally, the effectiveness and rationality of the proposed control are verified in MATLAB.关键词
