Total production cost c. system frequency and terminal voltage d. system frequency aloneSuppose a power system consists of two isolated regions: a western region and an eastern region. Five units have been committed to supply 3090 MW as shown below. The two systems are separated by a transmission line that can handle a maximum transfer of 550 MW in either direction. If losses are ignored, calculate the spinning reserve for the overall system and for each region. Comment on the adequacy of the spinning reserve of the overall system, and for each region. (consider the effect on the power supply in each of the regions if the various generators fail). Repeat the above calculations and analysis if an average of 8% of the output of the generators is lost in the transmission and distribution system before reaching the load.
