基于双人零和博弈的孤岛微电网有界L2增益负荷频率控制OA北大核心CSTPCD

Focusing on the islanded microgrid with uncertain modelling error and renewable energy integration,an integrated load frequency control(LFC)method combining the bounded L2-gain baseline control and disturbance compensation is proposed.First,the full-actuated model of microgrid is derived,and the influence of modelling error and renewable energy is summarized into an integrated disturbance.To improve the system robustness,the integrated disturbance is defined as the opponent of the control signal.Further,the bounded L2-gain problem regarding the disturbance suppression is equivalent to solving the Nash equilibrium of zero-sum game between the integrated disturbance and the control signal.Thus the bounded L2-gain baseline controller is derived.To improve the secondary frequency regulation,a disturbance compensation control based on the fifth-order generalized integral observer is designed.And a new anti-GRC measure for generation rate constraint(GRC)is introduced on this basis.Finally,a 16 MW renewable energy-diesel hybrid microgrid simulation model is constructed,and the proposed integrated LFC method is tested under various operation conditions to verify its effectiveness.
