Hybrid power plant control: solar, storage and gensets working as one system

A hybrid plant is not defined by having several sources on one site, but by one control logic coordinating them. BST.SOLAR designs and commissions ComAp InteliNeo-based control systems that manage PV production, battery state of charge, genset run-time and grid limits at the same time – at second level, without manual intervention.

When do you need hybrid control?

  • Hybridising an existing plant: a PV, gas-engine or diesel site is extended with storage and the two systems must be controlled together (for example Domaszék).
  • Grid-connection limit: the storage absorbs surplus production and the controller holds the permitted power at the connection point.
  • Island operation or a weak grid: the genset starts only when the state of charge and the production are not sufficient – minimum run-time, less fuel.
  • Several generating units in parallel: load sharing and synchronisation of genset groups, PV inverters and PCS units, black start.

How our hybrid control is built

1. ControllerComAp InteliNeo 5500/6000 microgrid controller or InteliNeo 530 BESS, depending on site size and the number of gensets.
2. CommunicationModbus / IEC 61850 links to PV inverters, PCS, BMS and the grid meter; InteliGateway 300 for cloud monitoring.
3. LogicSite-specific modes: export limitation, peak shaving, self-consumption, genset-saving operation, voltage and frequency support.
4. SupervisionEvent logging, alarms, remote diagnostics and engineering support.

All of this is also available pre-assembled and factory-tested: the BST Control Box is the ComAp InteliNeo-based EMS controller in a cabinet, at a fixed price. BST Control Box details →
