Urban grid resilience in the context of new infrastructure

Urban power grids are characterized by a bulky concentration of different load zones (commercial, industrial, and residential) and strict requirements on the grid resilience and reliability of power supply from distribution systems. The increasing power demand, due to the population and economic growth, is pushing the operation of urban power grids to its capacity limits. The installation of distributed energy resources (DER) like photovoltaic (PV), wind power, and energy storage (ESs) with proper control and coordination mechanisms can offer a possibility to improve grid resilience. In this chapter, emerging coordination utilizes dispatchable sources to enhance the restoration capability under different disruptive events such as grid malfunctioning, severe weather, malicious attacks, and operation missteps. These coordinated control methods are based on a multiple-time-scale hierarchical framework that can effectively manage a complex, multi-target requirement of grid resilience.
