- Summary
-
The planning, design and operation of electrical grids have become particularly challenging in recent years. This is due to, in no small part, the prominent presence of wind and solar generation in the grids. These sources are weather-dependent, uncertain and difficult to predict accurately. As a result, often the renewables are considered non-dispatchable generators. The uncertain renewables often exacerbate the mismatch between the generation and demand, spatially as well as in time. In this talk, a frequency-domain approach to analyze the renewables shall be presented. From the implicit mode functions obtained from the analysis, it is shown how the resiliency of the grid system can be improved by the suitably- controlled buffering actions of energy storage systems, in which the storage elements are to undertake the power bridging, power quality enhancement or energy management roles. Several examples of such applications shall be described, including that of the New Zealand grid system in which a pumped-hydroelectric system shall be utilized to buffer the seasonal generation-demand imbalances, with the view to achieve zero-carbon power generation through the integration of large-scale wind and solar generation into the grid.
