The goal of the PRIMO project is to create a platform for interconnected micro-grid operation. This platform will be capable of maintaining safe operation of the local micro-grid by
cost-optimal control of flexible distributed energy systems (DES), i.e. waste-to-energy (W2E) systems, battery energy storage systems (BESS), demand side flexibility (DSF) and vehicle-to-grid (V2G) systems,
coordination with neighbouring micro-grids, and
participation in the national electricity market.
The framework is to be demonstrated for a study area at Punggol in Singapore within the intended Punggol Digital District (PDD) micro-grid system.
The project comprises four sub-projects:
In sub-project 1, a good understanding of the underlying electric grid and uncontrollable DES is developed by modelling traditional loads and photovoltaic (PV) installations in the study area.
In sub-project 2, future scenarios and models for flexible DES, i.e. V2G-enabled electric vehicle (EV) charging as well as DSF in air-conditioned buildings, are formulated for the study area. Furthermore, the user behaviour and social acceptance of the proposed flexible DES is investigated.
The control methods for local micro-grid operation are developed with a focus on cost-optimal operation and its implementation on the test bed in sub-project 3.
In sub-project 4, the coordination framework and communication protocol for neighbouring micro-grid interaction is designed.
