and pricing in the new environment of electricity market. Spinning reserve
is one of the most important ancillary services needed for satisfying
reliability requirements as well as desired level of security in power
systems. In deregulated power markets, generally two methods for energy
and spinning reserve dispatching are addressed the so-called sequential
dispatch and joint dispatch. It can be said that the sequential dispatch
method may not be even feasible as well as optimal because of the coupling
between spinning reserve and energy capacity. Therefore, in this study,
a new method is proposed for dynamical joint energy and reserve dispatch
that can solve the bottling of reserve problem by considering transmission
limits. A genetic algorithm as an evolutionary optimization technique
is used to solve such a complicated and non-convex problem. The proposed
methodology is applied to a typical IEEE 30-bus system, while simulation
studies show the effectiveness of joint energy and spinning reserve dispatch
in comparison with the sequential dispatch.]]>Asadi, B.M., M. Rashidi-Nejad and M. Pourakbari,20082008Baskar, S., P. Subbaraj and M. Rao,200329407419Chen, J., J.S. Thorp, R.J. Thomas and T.D.
