Research on multilevel control technology for new energy stations based on GOOSE
As large-scale new energy stations rapidly develop and expand,the traditional power control systems,with their single-tier communication architecture and control strategies,are proving inadequate for the demanding frequency regulation and voltage control requirements of these stations.To address these problems,this study proposes a novel communication architecture based on(generic object oriented substation event,GOOSE)technology.The architecture comprises four layers-the cluster control system layer,station master layer,station slave layer,and station single machine layer-and operates across three networks corresponding to these layers.The principles and components of both the hardware and software within this architecture are elaborated upon.Additionally,the study briefly introduces the logic behind the wind-solar-storage coordinated control software.The efficacy of this approach is tested at a photovoltaic station,focusing on the integration and power testing of a new master-slave configuration active support device.The results demonstrate that the master-slave configuration at the station level can provide rapid and effective control support for both frequency and voltage,aligning with national standard requirements.
