Starting up rapid-start units for energy and reserve contributions

This paper presents the effect of the start up failure probability or the starting reliability of rapid-start units such as open-cycle gas turbines on energy scheduling and reserve allocation. The reserve allocation to these offline rapid-start units are in term of non-spinning reserve. A joint probability distribution approach is used to integrate the starting reliability into the operating reliability. This work studies the effect of the starting reliability on the system economic and reliability of a power system. It illustrates that the system reliability deteriorates when non-spinning reserve is allocated to those rapid-start units with poor starting reliability.
