AI Technical Summary

Technical Problem

Distributed photovoltaic systems suffer from problems such as inconsistent equipment specifications, chaotic addresses, poor coordination of control commands, and contradictions between grid loss and power consumption, resulting in high difficulty and cost of retrofitting and commissioning. Furthermore, traditional retrofitting solutions are complex and inefficient.

Method used

A distributed photovoltaic controllable method based on protocol self-identification and address-assigned control is adopted. By designing a 12-bit unified address code and a 4-bit control attribute field for each user unit, a 22-bit complete identification code is constructed, an address mapping database is built, and protocol self-identification and address matching are realized in combination with a centralized management platform. The optimal control command sequence is generated by using hybrid integer optimization and reinforcement learning algorithms, which supports accurate positioning and command coordination of cross-regional equipment.

Benefits of technology

It achieves self-identification of mainstream inverter protocols, reduces operation and maintenance costs, improves the accuracy of equipment management and control and the level of large-scale regulation, balances minimizing grid loss and maximizing photovoltaic consumption, simplifies wiring and installation, is compatible with equipment from multiple manufacturers, and has strong scalability.

Abstract

This invention discloses a distributed photovoltaic (PV) controllable method based on protocol self-identification and address-based control, applicable to multi-user PV systems. The method achieves protocol self-identification by configuring a protocol converter and establishing an online-updable standardized protocol database; it constructs a 22-bit complete identification code containing a 12-bit address, 4-bit control attributes, and a 6-bit area identifier, and builds an address mapping database; relying on a centralized management platform, it constructs a dual-objective optimization model of minimizing grid loss and maximizing PV grid integration, solves for the optimal command through reinforcement learning, and distributes the command hierarchically in conjunction with the identification code. The system includes protocol adaptation, address encoding and mapping, centralized management and control, and execution control modules. This invention improves the accuracy and efficiency of control, reduces grid loss, and increases PV grid integration rate.
