Practice of microgrid control system

摘要

The system is based on the characteristics of microgrid and energy storage power plant control system, combined with engineering practice, providing monitoring for the island-based independent power supply systems, science parks, research institutes, laboratories microgrid, energy storage power stations, control, protection and energy management integration solutions. For system integration process, control equipment and integrated communication protocol differences difficulties brought by reference to IEC61850 specifications for device modeling and functionally related logical nodes (Logical Node, LN) carried out the necessary expansion of the unified communications follow IEC61850 specification. System uses a multi-division, multi-modal coordination and management structures and ways of using programmable logic and network operation, as well as isolated operation mode switching operation mode strategies to build the library organized package to meet the needs of different projects and projects. Through various forms of microgrid internal energy and load forecasting and scientific precision scheduling, coordination and optimization of microgrid and microgrid, microgrid and large grid network to achieve energy efficient use of energy to meet a variety of user needs, improve supply reliability and other purposes.
