A SPORE Study: Microgrid Sizing Analyses and Use Cases (Room Garuda 9, 1st Floor)

Microgrid sizing is one of the most important aspects to assess the feasibility of deploying microgrid projects. Being part of the largest hybrid microgrid test and research platform – the Renewable Energy Integration Demonstrator-Singapore (REIDS) initiative – ENGIE is building a multifluid microgrid for Project Sustainable Powering of Off-grid REgions (SPORE) on Pulau Semakau to look into providing different solutions for off-grid microgrids including sizing for such microgrids. With the installation ongoing on the island at the same time, sizing studies have been conducted based on the SPORE microgrid – a multifluid microgrid which consists of diesel gensets, photovoltaic (PV) panels, Li-ion battery energy storage systems, mid-size wind turbine, H2 power-to-power system. A pre-sizing tool is developed by ENGIE to minimize the levelized cost of electricity (LCOE) over the project life time to give the optimal sizing for each component in the multifluid microgrid. Several sizing examples are given and analyzed to justify the philosophy of the results of the sizing tool. Case studies from sizing of a kW-scale microgrid for a resort based on real load profile and seasonality to the possibility of sizing a MW-scale small utility hybrid system are presented. Practical data will be obtained from the tests in the SPORE microgrid to verify and fine tune the developed sizing tool.
