Book Description
In Chapter 4, we study the capacity region and the dynamic stabilizing control policy for the PL queueing networks with time-varying channels. Based on the Lyapunov drift method, we propose a dynamic routing and power control policy, i.e. DRPC-PL, which stabilizes the network whenever the input rate is within the capacity region of the PL queueing network. The Smart Grid system is a future vision of the electric power system, which features interaction and communication among grid components, adaptation of renewable energy and reliability/self-healing, etc. In Chapter 5, we consider the integration of stochastic wind power generation in the Smart Grid under renewable portfolio standard (RPS) with deep wind penetration. For small-scale utilities installed with wind turbines and acting as distributed energy resources (DERs), wind energy can be potentially integrated to satisfy customer power demand or enter energy market. To exploit the temporal variation of system status and real-time electricity market, we propose a theoretical framework to dynamically determine the role of wind energy and provide long-term RPS guarantee. This approach yields a simple dynamic thresholding control under the assumption of system ergodicity, which maximizes the expected profit of the utility and is easy to be implemented online.
