An EMU300-based energy management system for distribution areas, low-voltage storage and distributed sites. Single-cabinet autonomy, ring-network expansion and cloud-edge coordination address overload, three-phase imbalance, low voltage, PV consumption and charging-load impact.
Addressing distribution-area overload, three-phase imbalance, low voltage, PV reverse feed-in and high retrofit costs, the solution uses the EMU300 on the distribution-area side for per-phase control, SVG dynamic reactive power, reverse-power protection and dynamic capacity expansion. In the cloud, operating status, alarms, revenue and adjustable capacity are viewed in one place, providing the data basis for power-supply assurance, consumption and VPP aggregation.
A cloud-edge-device coordination solution connecting site control, remote O&M and revenue review.
/ Power / Dispatch, improve Capability
Transformer loading can reach 110%–130%, increasing expansion pressure.
Dynamic capacity expansion and multi-cabinet parallel operation reduce upfront investment.
Imbalance above 20% increases neutral-line losses and shortens equipment life.
Independent phase control and SVG compensation improve feeder power quality.
End-of-line voltage can fall to 180–198 V and affect user-side equipment.
Edge load-status monitoring coordinates active and reactive power to support voltage.
High PV penetration creates curtailment and reverse-power risk.
Coordinate PV, SOC and reverse-power protection to improve local PV consumption.
Traditional distribution-area upgrades cost more and take 3–6 months to approve and build.
Use edge storage control and cloud operations to defer heavy infrastructure expansion.
A cloud-edge coordinated system connecting project deployment, site control, cloud review and long-term operations.
In the system architecture, the dispatch centre and FeiCloud/VPP connect to EMU300 ring-network nodes via 4G/5G/optical fibre, and each cabinet independently manages the energy of its own cabinet.

Dynamic expansion defers traditional transformer investment.
One controller replaces multiple conventional devices.
Aggregated sites can participate in power-market services.
Purpose-built for distribution-area storage scenarios and suitable for 125 kW / 261 kWh distribution-area storage cabinets, it supports edge autonomy, phase-independent control, ring-network cabinet parallelisation, VPP access and the IEC 61850/104 protocols.
During peak-load periods, energy storage compensates for the distribution area's shortfall, deferring conventional capacity-expansion investment and reducing the impact of outage-related construction.
Energy storage charging and discharging plus reverse power-flow control improve the local consumption of distributed PV.
