Module 5: Real and Reactive Power Scheduling Lecture 22: Real Power Scheduling 
 
Merit Order Dispatch: 
The simplest real power scheduling problem can be formulated by assuming the following: 
a) The generators which are "committed" are known (the issue of whether to engage a generation unit and 
for what duration, based on cost and prime mover/energy supply constraints is not considered here). 
b) The generation cost (per kW-hr) for various generators is constant. 
c) No inequality constrain...

Module 3: Frequency Control in a Power System 
Lecture 11: Definition of Frequency 
 
What determines grid frequency?s 
While it has been stressed that frequency is the same in a steady state throughout a synchronous grid, two very interesting questions need to be answered: 
What is the precise value of frequency to which a system will settle? 
How does the "system frequency" vary during transients? How can one obtain a useful frequency definition when individual generator speeds differ durin...
