Frequency control is essential to maintain the stability and reliability of a power system. Traditionally, primary/secondary/tertiary reserve services with fossil-fuel based generation units are used to stabilize the power system frequency upon a contingency of supply-demand power imbalance, which, however, incur high operational costs. In future smart grid, demand response (DR) is an effective method to control the power consumption of distributed users in real time, which can be utilized to stabilize the power system frequency at low cost. This thesis is devoted to investigating efficient algorithms for DR-enabled distributed frequency control in smart gird.
This thesis starts with proposing a new frequency control algorithm based on randomized on-off operation of distributed smart appliances (SAPPs), to stabilize the power system frequency without the need of conventional primary reserve service. (Abstract shortened by UMI.)
