| Summary: | This report sheds light on the challenges of integrating solar energy into Singapore's power
infrastructure and provides insights into how this can be achieved with DC distribution
networks. There are potential impacts on the DC distribution networks by incorporating
solar energy and DC loads such as electric vehicles (EVs). Grid’s operating frequency
deviation may be improved, and the mechanical power required for electricity generation
can be reduced. Furthermore, the use of DC loads can increase the overall efficiency of
Singapore's power system while reducing its carbon impact. This report also explores
modeling methods and frequency control techniques to maintain grid stability in real-world
implementations involving load demand and conventional synchronous machines. This
will reflect the potential increase in demand from the growing EV population and EV
chargers. Additionally, the report considers the use of inverter-based resources.
