A risk-based approach for provision of Spinning Reserve by means of Emergency Demand Response Program

Spinning Reserve (SR) is one of the ancillary services which is essential to satisfy system security constraints when the power system faces with a contingency. In this paper, emergency demand response program as one of the incentive-based demand response programs is implemented as a source of spinning reserve. In this regard, certain numbers of demands are selected according to a sensitivity analysis, and are simulated as virtual generation units. The reserve market is cleared for SR allocation considering a probabilistic technique. A comparison is conducted between the absence and existence of emergency demand response program from both economical and reliability view points. Numerical studies based on IEEE 57 bus test system are conducted for evaluation of the proposed method.
