Energy storage is becoming an attractive solution for today’s smart grid, either being operated independently as asset or interacting with other resources like wind/solar generation or demand response. This tutorial provides participants a solid understanding on the basics and the state-of-the-art energy storage application, its implications on the grid’s reliability and the system’s economics and how-to on evaluating its performance and cost-benefit. Instructors with diverse backgrounds on this subject will bring the field deployment experience of energy storage applications and the real-world example to demonstrate the analytic tools in assisting the utility planning and operation decisions. The course is suitable for non-technical, as well as technical audiences, including regulatory, legislative and utility staff members.
