Future Power Grid Solutions and Energy Storage
Singapore’s power system will become more complex as it integrates greater amounts of solar energy, energy storage, electricity imports, and distributed energy resources. Much of this new capacity connects through power electronics rather than conventional generators, and much of it sits at the edge of the distribution network rather than at central plants — so the grid must stay stable with less of the inertia conventional generation has always provided, and operators must ‘see’ and control assets they have not historically monitored.
Demand is changing at the same time. High-power loads such as data centres can be completed far more quickly than the transmission and distribution infrastructure needed to serve them. Land constraints compound this problem, as energy storage systems and grid infrastructure compete for space with every other use in a city-state.
AEDO’s research focus is therefore on the technologies needed to maintain power-system reliability and resilience, and to connect new capacity quickly within Singapore’s land and cost constraints. Our R&D strategy addresses the following challenges:
Real Time Visibility and Control and Inertia Building in Singapore’s Grid
Challenge statement: Enable near real-time visibility and control over load and energy sources at the edge of the distribution network, in order to better support integration of new energy sources (solar PV, batteries) and load types (e.g. electric vehicle fast charging) into the grid.
Challenge statement: Balance and stabilise the grid, such as synthetic inertia-providing technologies or fast-responding assets that actively adjust power output to address mismatches in power supply and demand.
Energy Storage Integration Solutions
Challenge statement: Reduce land usage for energy storage systems whilst maintaining equivalent energy density and safety standards.
Speed to Power
Challenge statement: Reduce construction time, land take, and cost of grid transmission and distribution infrastructure to facilitate timely and cost-effective connection of high-power loads (e.g. data centres) to the grid.
Challenge statement: Develop modular and stable low-carbon power solutions that can be economically and quickly deployed to meet existing grid constraints.
