MPS-250 250 kW Energy Storage Inverter

For Behind the Meter and Microgrid Energy Storage Applications


FCompECompactive_standbydynamictransfer For 600 VAC class grid connected energy storage applications, Dynapower offers its Micro Power Systems™ (MPS) family of utility grade, bi-directional, true four-quadrant, high efficiency, Digital Signal Processor (DSP) controlled inverter/converters. Dynapower’s flexible and modular MPS optimizes the transfer of energy between a DC energy storage system and a single or three phase grid. The MPS provides power conditioning (voltage and frequency support), VAR support, & Standby UPS capabilities for intermittent loads and renewable generation. Systems are available in indoor and outdoor configurations. The MPS integrates controls and a full complement of switchgear and protection including an AC circuit breaker, AC contractors, AC & DC Fusing, DC load break contactors, and a DC manual isolation switch into a single, heavy duty industrial enclosure. certifications D O W N L O A D ► MPS_250.pdf (317 downloads)   TWO_MODES_ICON

The MPS provides two modes of operation; Grid-Tied (PQ mode) and Stand-Alone or Islanded (UF mode). In the Grid-Tied mode, the MPS controls the AC output real power (P) and reactive power (Q). In Stand-Alone mode, the MPS controls the AC output voltage (U) and frequency (F). The system can be started in either mode and the transfer between modes is done dynamically. The transition between operating modes is automatic upon loss and the return of grid. When transitioning to an islanded mode, the AC voltage shall be stable in less than 2 cycles. For islanded to Grid-tied operation, transfer will be complete in less than one cycle.

Advanced control schemes for multi-unit and micro-grid applications are available.

The MPS provides full system status information including AC output real & reactive power, AC output voltage & frequency and DC battery voltage and DC current readings to the remote operator through feedback signals or through the communication link (via an RTU or PLC). The MPS has an on-board monitoring system with error history and grid fault data capture.

The standard cooling system utilizes natural convection for cooling of AC epoxy cast inductors and IGBT heat sinks. In optional forced air-cooled supplies, cooling of the enclosure is accomplished using temperature-controlled fans with air intake via louvers at the base of each door and customer specified side or top exhaust.
