Dynamic Control of Electricity Cost With Power Demand Smoothing and Peak Shaving for Distributed Internet Data Centers

Free registration required

Executive Summary

Internet based service providers, such as Amazon, Google, Yahoo, etc, build their Data Centers (IDC) across multiple regions to provide reliable and low latency of services to clients. Ever-increasing service demand, complexity of services and growing client population cause enormous power consumptions by these IDCs incuring a major part of their running costs. Modern electric power grid provides a feasible way to dynamically and efficiently manage the electricity cost of distributed IDCs based on the Locational Marginal Pricing (LMP) policy. While recent works exploit LMP by electricity-price based geographic load distribution, the dynamic workload and high volatility of electricity prices induce highly volatile power demand and critical power peak problem.
