In the wake of multi-day power outages due to severe weather events in recent years, OER sought consultant support for design of a program intended to enhance the energy assurance of critical infrastructure through …
The first challenge is to provide an efficient optimization model for the operation and management of energy in island microgrids, which improves the important indicators of the microgrid in addition to supplying the load. Modelling should be for day-ahead (24 hours) and include DG resources, ESSs, demand-side management and …
The electrical grid exists to supply our electricity demand, ensuring the two are balanced and connecting electrical supply to electrical demand with the transmission and distribution system. In practice, a microgrid works in the exact same way, just for a smaller geographic area, like a couple of buildings or a local community.
Its herald is the microgrid: combining generation, distribution, consumption and storage at a local scale, under the aegis of advanced monitoring, control and automation systems. Island microgrids are placing self-generated electricity into the hands of local communities – and reworking traditional energy infrastructure from the bottom up.
The company plans to build a small-scale microgrid system centred on public facilities, which have several hundred kilowatts demand.
