Dynamic Economic Dispatch Scenario Planning for Power Grids with PVs and Storage

With increasing penetration of solar photovoltaic (PV) in Singapore, the adoption of energy storage systems (ESS) is inevitable to mitigate the uncertainties arising from solar PV. This paper aims to analyze the role of two main battery technologies, namely Lithium Ion (Li-ion) and Vanadium Redox Flow Batteries (VRFB) in meeting Singapore’s 1 GWp PV installation target beyond 2020. The economic implications of solar PV and ESS integration into the Singapore grid are studied using a cost-based dynamic economic dispatch model for scenario planning at various levels of solar PV and ESS penetration level.
