## Project Overview: A Customized Microgrid for a Challenging Power Environment
Inedge Power (雅集能源) has completed factory commissioning and shipped a customized 1.5MW/5MWh energy storage system for a customer in Eastern Europe. The system will connect to a 1600kVA, 0.4kV transformer at the customer's factory, forming an integrated microgrid combining PV, energy storage and diesel generators to safeguard local production and daily electricity use.
The power environment in Eastern Europe is highly challenging, with frequent grid fluctuations. The customer set clear and demanding operational requirements for the storage system—requirements that shaped both the system design and the factory testing.
## Complex Application Scenarios Demand a "Smart" System
The customer's requirements were specific and practical:
Highly flexible charge/discharge strategy. The project sets a maximum charging power of 1500kW and a grid-connected output of 750kW, with both charging and discharging power adjustable in real time through the EMS.
Grid-forming capability. The system must support both grid-connected and off-grid modes, and must be able to directly connect to and control diesel generators.
Practical EMS energy management logic. During the day, PV supplies the load first, with surplus power charging the battery. At night, the battery discharges to serve the load, minimizing diesel generator use. When PV output is insufficient or battery SOC is low, the system automatically starts the diesel generator to supplement power. This PV-storage-diesel coordination logic directly affects the customer's actual energy costs.
## Factory Testing: Hard Focus on Switching and Grid-Forming
Given the project's specific requirements, factory testing focused on two hard indicators: on/off-grid switching and grid-forming load carrying.
In the test workshop, engineers simulated the extreme condition of a sudden grid outage. Based on the PCS's grid-forming control technology, the system instantly established voltage and frequency in off-grid mode, stably carrying the load with millisecond-level switching. Engineers then connected the diesel generator to the system, repeatedly verifying the EMS dispatch logic under complex conditions such as PV fluctuation and low battery SOC—ensuring the diesel generator's start-up, grid connection and withdrawal were smooth throughout, without circulating current impact.
## Customized EMS: Making Every Kilowatt-Hour Count
The core of this system is Inedge Power's deeply customized EMS. It does more than control charging and discharging—it coordinates an entire microgrid. By monitoring PV generation power, battery SOC status and factory load changes in real time, the EMS automatically calculates the optimal power allocation plan. In off-grid mode, it can also automatically adjust discharge power according to the plant's real-time load, making the storage system the stabilizing anchor of the factory microgrid.
## Ready for Shipment: Expanding Overseas Markets and Advancing Storage Project Delivery
In the dispatch area, the system cabinets have completed moisture-proof and waterproof packaging. This is not only another successful delivery for Inedge Power in the European market, but also a direct demonstration of our technical strength in complex microgrid applications.
After the equipment arrives at the Eastern Europe site, only transformer connection and communication commissioning are needed before it can be put into operation. From the Chinese workshop to Eastern Europe, Inedge Power will continue to provide overseas customers with safe, stable green energy support through hardcore grid-forming technology and intelligent energy management.
