With the spotlight on smart grid development around the world, it is critical to recognize the key factors contributing to changing power-system characteristics. This is more apparent in distribution systems with the integration of renewable energy sources, energy storage, and microgrid development. Source and load control at the distribution level is a key requirement of the evolving system. These activities require distribution automation (DA) strategies that take advantage of available technologies, while promoting newer solutions. It is necessary to create a roadmap for holistic DA strategies in a smarter grid. Sustainable and resilient grid development is a paradigm shift requiring a new line of thinking in the engineering, operation, and maintenance of the power system. Distributed control architectures based on dynamic load and source data should be explored as a possible solution. This paper discusses a novel approach that integrates protection, control, and monitoring using high-performance computing at the primary distribution substation level. The business case for infrastructure investment in the distribution systems is also discussed. This paper concludes with a discussion on emerging and future technologies for DA to improve the resiliency of a sustainable grid.
