SMART FLEXIBLE DISPATCHABLE TRANSMISSION SERVICES AND FLOWGATE BIDDING IN SECURITY CONSTRAINT UNIT COMMITMENT %K Smart flexible transmission service %K flowgate bidding %K dispatchable transmission services %R 10.22099/ijste.2013.1759 %X To attract more investments for developing smart transmission networks and increasingtheir flexibility and efficiency, recently policies have been suggested which provide financialincentives in transmission network investment. One of these policies is price biding forincremental transmission capacity and transmission elements in power markets. According toFederal Electricity Regulatory Committee, flowgate bidding is defined as allowing a line’s flow toexceed its rated capacity for a short period of time for a set penalty, i.e., price. This paperconcentrates on the development of a comprehensive model for flowgate bidding and DispatchableTransmission Services (DTS) in security constraint unit commitment.DTS and flowgate biddings are used during contingencies and steady state to determineoptimal required energy and reserve values. As the scale of the problem is large, the bendersdecomposition algorithm is used to solve the problem. To investigate the efficiency of theproposed strategy, IEEE 6 and 24 bus case tests are studied. According to the obtained results, thisstrategy decreases energy and reserve marginal prices, as well as reliability cost. Furthermore, thesuggested plan is an incentive to the owners of transmission companies. %U https://ijste.shirazu.ac.ir/article_1759_ede209ec754b49dfc12931e49bc4cb28.pdf
