• Central controller
• Demand management
• Energy management
• Hierarchical control
• Microgrid in the park

Aiming at the problems of higher cost, different standards, low integration, and lack of practical operational energy management strategies for microgrid controllers, a microgrid central controller integrating measurement, monitoring and energy management is designed. The controller utilizes ARM-based embedded system hardware platform and modular design. Considering the energy needs of enterprises in the park, some new energy management strategies according to the unique characteristics of the park are designed. The demand forecast based on the triple exponential smoothing method is proposed and the energy storage system is used for demand management to reduce the electricity cost of the enterprise without affecting the business and production. The function and energy management strategy of the central controller are also proved by establishing a physical experiment platform, showing its better practicality.
