This paper undertakes the problem of optimal capacitor placement in a distribution system. The problem is how to optimally determine the locations to install capacitors, the types and sizes of capacitors to he installed and, during each load level,the control settings of these capacitors in order that a desired objective function is minimized while the load constraints,network constraints and o...

Capacitors in power systems are generally used to supply reactive power to reduces losses and improvement of the voltage profile.The appropriate placement of capacitors is also important to ensure that system power losses and total capacitor costs can be reduced. This paper presents a new constraint objective cost function to maximize the net annual savings by minimizing real power loss and opt...
