Solution Overview
EMS SOLUTION
Customer Pain Points
Multi-energy strategy is complex
PV, storage, diesel generators, and utility grid can all affect operating targets.
Grid-connected and islanded goals differ
Grid mode emphasizes economy and consumption, while islanded mode emphasizes reliability and SOC boundaries.
Critical loads need priority
Hospitals, mines, and island sites require clear critical and normal load priorities.
Diesel generator operation is costly
Generator start/stop should be reviewed against load and storage status.
PV fluctuations need balancing
Storage or generators may be needed to balance PV output and load changes.
Islanded operation requires continuous monitoring
Power sources, loads, SOC, and alarms need close tracking when isolated.
EMS SOLUTION
Solution Description
Microgrid EMS connects PV, storage, diesel generators, utility grid, grid switches, critical loads, normal loads, meters, PCS, BMS, and inverters for multi-energy operation.
Control goals differ by mode: grid-connected operation focuses on cost and PV consumption, while islanded operation focuses on critical-load supply, generator support, and SOC boundaries.
Microgrid energy flow, load priority, generator records, and islanded-state monitoring help operators balance cost, reliability, and safety.
