Abstract
This paper develops a novel strategy for the expansion of the power system corridors for the release of the embedded transmission capacity. Both theoretical and practical network models are presented with a focus on power flow studies which concentrates on the steady state or static behavior of electrical power system. The methodology involves the power flow analysis revalidation of the existing standard IEEE 14 bus system and simulation using Newton- Raphson method in both MATLAB and Powerworld simulator (PWS) environment. This paper therefore establishes that an original designed network could be modified to take more loads without building new generators or transmission lines. The expansion of the existing IEEE 14 bus network to accommodate more load involves the use of static compensators incorporated at the transmission lines. This technique is then analyzed extensively when distributed along the lines through the use of a distributed capacitors compensators, (DCC). DCC can affect significant change in power line impedance to improve the power transfer capacity of an interconnected power system. The application of the DCC on the line is the tier-1 technique. The results obtained show that by applyingthe tier-1 techniques to the transmission line, the system’s capacity will remarkably improve and the transmission line will accept extra loading.

Investigations are done in this paper to see how capacitors distributed along the transmission lines can expand the transmission line corridor by the release of embedded transmission capacity
Summary
Reactive power compensation otherwise called reactive var compensation is the management of reactive power to improve the performance of AC power systems, maximizing stability by increasing flow of active power. There are many different methods used for compensation in power systems Some of these methods include reducing generator and transformer reactance, increasing the number of parallel lines used, using shunt capacitor compensators, or using series capacitor compensators [5]. Improves voltage regulation Expand power transmission corridor of the transmission line Improves system stability The applications previously mentioned are merely a selected few of the uses that DCC devices can provide. These applications and others are used throughout the world to improve the system as a whole.
