and Yusuf Al-Turki. They discuss the
challenges of renewable proliferation
as well as opportunities for expanding
the use of renewable energy. One
example is the lack of ramping flexibility of grid-following renewables for
power system operation. This shortcoming can be mitigated by having
energy storage systems and renewables working as a unit to achieve
grid-forming functions and further
participate in demand response. To
this end, data analytics, information
technology, and communication
technology with cybersecurity will
facilitate the end uses to have the
demand-response capability. Those
technologies help solar PVs work with
not only static energy storage systems
but also electric vehicles.
Finally, "A Controller Hardwarein-the Loop Testbed," by Siddhartha
Nigam, Olaoluwapo Ajala, and Alejandro D. Domínguez-García, presents a lab testing setup to examine
the performance of centralized
and decentralized microgrid control architectures.
