Overview

Lingqi’s New Energy PV & Storage Turnkey Secondary System delivers end-to-end services for photovoltaic and battery energy storage projects, covering the full spectrum of secondary system requirements. From telecontrol and local monitoring to AGC/AVC automatic generation control, dispatch data communication, grid cybersecurity, and cloud platform integration, Lingqi provides a single-vendor solution that eliminates multi-vendor integration complexity. The solution is designed for both standalone PV stations and integrated PV-plus-storage projects at voltage levels from 10kV to 110kV.

The architecture centers on Lingqi’s PBox series communication manager, which consolidates functions that traditionally require 4-5 separate devices. Key subsystems include: the telecontrol subsystem for real-time data acquisition and IEC 101/104 dispatch reporting; the AGC/AVC subsystem that receives grid dispatch setpoints and automatically distributes active/reactive power across inverters and PCS units; the cybersecurity subsystem with vertical encryption and horizontal isolation; and the cloud integration layer that pushes operational data to owner O&M platforms and mobile applications.

Lingqi has delivered this turnkey solution to dozens of PV and energy storage projects nationwide. Performance tracking shows the integrated approach reduces secondary system deployment costs by 40%, shortens commissioning-to-grid-connection cycles by 30%, and improves overall system reliability through reduced component count and single-vendor accountability.
