摘　　要：拒绝服务攻击是近年来频发的攻击手段,其会对新能源电力系统频率控制等方面产生负面影响,进而影响电力系统的稳定运行。为解决上述问题,以光伏接入电力系统为例,首先根据光伏频率响应和DoS攻击模型,建立了DoS攻击下的区域电网负荷频率控制模型,并分析了攻击对光伏频率响应的影响,然后采用模型预测控制策略实现DoS攻击的防御,最后在MATLAB/Simulink中搭建了相应的频率仿真模型,验证了上述方案的可行性与有效性。Denial of service(DoS)attacks are a frequent attack method in recent years,which can have a negative impact on the frequency control of the new energy power system and affect the stable operation of the power system.To solve these problems,the photovoltaic(PV)power system was taken as an example,firstly,according to the PV frequency response and DoS attack model,the regional grid load frequency control model under DoS attacks was established,and the impact of the attack on the PV frequency response was analyzed;then,the model predictive control strategy was adopted to achieve the defense against DoS attacks;finally,a corresponding frequency simulation model was established in MATLAB/Simulink,to verify the feasibility and effectiveness of the above solutions.
