Microgrids and Renewables

The microgrid technology available today offers increased resiliency, lowers energy costs, and helps meet sustainability objectives.  WES.net works within the energy network to explore how critical facilities can leverage new technologies for improved resiliency. 

Microgrids are imperative to the existing energy grid for maintaining power.  Continuity of operations in critical facilities in the face of recent natural disasters have made it evident that long-term outages of the commercial power grid can be devastating.  Additional threats from manmade and natural electromagnetic pulses create uncertainty in power stability.

When deployed, independent modular microgrids rely wholly on operational inputs for island operation. A protected out of band management network connects the islands to form a type of archipelago for coordinated operations and situational awareness.

 

DC Coupled Microgrids

Through use of today’s new technology in modularity, high voltage DC power, and flexible distribution, the arrangement is designed to deliver maximum power with minimum energy consumption. In addition, minimum and simplistic maintenance and scalable growth can be adapted and changed to match future business opportunities.

  • Eliminate stranded capacity: distribution topology simplified from the top end through distribution to the end rack location; traditional series distribution approach eliminated in exchange for parallel path approach; HVDC bus with grid control distributes resources as and when needed.
  • Enhanced reliability: parallel path eliminates series components (top-level dual bus topology in 2N architecture arrangement); renewables or alternate sources available to extend emergency operations; peak shaving and demand response capability for non-emergency use operation; fully regulated voltage to rack level regardless of sagging battery voltage.
  • Modular deployment: power block deploys in 50KW modules; Voltserver circuits deploy from the transmitter to rack in topologies from N, 2N, 2(N+1) or greater in 1kW blocks; voltage, frequency, and capacity for racks adjustable at any point in lifecycle by exchange of local rack receiver configurations.
  • Rapid delivery: modular power blocks and sub-modules can be added in live upgrade mode; utilization of DC Microgrid and Voltserver technology allows for 100% factory install and testing of components; commonality of components from small systems to large facilities; day one (1) install can be scaled without penalty to match load requirements and day two (2) and beyond modifications made without interruption with 100% re-use of existing equipment.
  • Flexible and adaptable: maintenance activities and expansion performed without load interruption; simple and safe installation and operation.
  • Re-useable/relocatable/recyclable: all components can be reused or relocated as necessary within the lifecycle of equipment regardless of facility arrangement; buildings, modules, power systems and distribution components interchangeable for installs spanning 50kW to 1.5MW; building components include a high content of recyclable material above traditional requirements.
