Electric distribution grid is operated under a number of constraints in order to deliver power at a certain quality and reliability level. Electrical devices, such as capacitor banks, voltage regulators, and load tap changers are employed by the utilities to facilitate and support the operation of the distribution grid, while respecting many constraints, such as maintaining an acceptable band of voltage magnitude and a certain level of power factor. Traditionally, these devices are operated under fixed schedules, based on time of day or some other local parameters, and their operations are disjointed from one another, resulting in a decreased overall effectiveness of operation. This paper presents an approach to realize an integrated control and operation of these devices that will enable a more optimal operation of the grid. Simulation studies are performed on the IEEE test feeder network and the results highlight increased efficiency of grid operation in terms of decreased line losses, increased power factor, and improved voltage profile.
