In this work, we study the energy-efficient resource allocation problem based on chance-constrained programming for overlay cognitive orthogonal frequency division multiplexing (OFDM) system. The objective function minimizes the total power consumption and the constraint conditions include the requirement of the system outage probability and the feasibility of the subcarrier allocation solution.

Flexible loads are important resources to help maintain the power balance of smart grid. However, the control center is not able to exactly sense and control them because of their large quantity and wide distribution. In order to get the flexible loads to participate in the dynamic power system look-ahead scheduling, this paper proposes a three-layer ‘centralized coordination, distributed control’...
