Research On AGC Control Strategy Of Interconnected Power System

With the development of modern power systems,not only the regional power grids need interconnection support,but also the power grid itself needs to coordinate development with new energy sources,which brings new challenges to the grid operation.These new problems are addressed through grid frequency control and precise load forecasting.Therefore,it is imperative to study an automatic power generation control system.Conducts a coherent study on its automatic power generation control strategy in an environment containing interconnected power systems with small-scale wind power.1)A mathematical model was built about the negligible secondary factors of the grid platform.In the environment where the scale of wind power was not large,the wind power area was added to the ordinary power generation system,and the negative load and the conventional thermal power unit and the hydropower unit were involved in the load frequency control.Constructed a wide-area power platform model with strong universal small-capacity wind power and common power generation systems.2)Based on the extremely strong robustness of the sliding mode variable structure control strategy,a load-frequency controller based on sliding mode variable structure was designed for interconnected power systems.In order to ensure the stability and feasibility of the sliding mode control system,the Lyapunov stability principle was theoretically verified.Simulation experiments showed that the designed control strategy had good universality and sensitivity.3)The SVM combination strategy based on deep learning algorithm coupled with particle swarm optimization was used to realize load forecasting.Used deep belief networks to mine deep implicit information of massive data.Based on the actual load data of the user,the validity of the above model was verified.This hybrid strategy could better fit the actual complicated function of mapping.Figure 26;Table 4;Reference 50...
