Assessment of spinning reserve under strategic bidding in a competitive energy system

In deregulated power systems, maintenance of sufficient security margin and reliability level are the major tasks of the independent system operator (ISO). The provision of bids change at any time in the competitive market makes the power injections and withdrawals are time variant and are mainly determined based on economic grounds only. In order to maintain security and reliability, the adjustable markets and ancillary service markets are also becomes an integral part in the general power market clearing mechanisms. This paper is addressing the combined market model to assess the spinning reserve (SR). The deterministic approach is adapted to require SR in the system. The competitive power market is applied to all the markets independently and later they are integrated in to one common optimal solution. The proposed approach is discussed on IEEE-14 bus system.
