IEEE 146 Bus Test System Research Papers (original) (raw)

Today’s bulk power system is massive, complex, and very dynamic. The U.S. power grid spans from coast to coast and even as far reaching as Canada. With the addition of new technologies such as renewable energies and power electronics to aid in power conversion and control, the power system grows more complex by the day. The most common approach of analyzing power system stability isthrough computer modeling and simulation. Due to the vast size and inaccessibility of transmission systems, real time testing can prove difficult. Themotivation of thisproject wasto design, simulate, and construct an IEEE 14 bus power system for future use in a lab setting to test, in real time, novel control techniquesfor various forms of generation and their impacts on the stability of the grid. This Paper presents the theory used to design and construct an IEEE 14-bus power system. A comparison of results from modeling and simulation with actual lab data obtained from the constructed test set up.

The power system enters a state of voltage instability due to the inability of the power system to meet the demand for active power and reactive power due to the increase of system load. In order to stabilize the power system, the installation of STATCOM and ESS needs to be performed. The main objective of this paperis to identify the suitable size and location of STATCOM and ESS for power system stability improvement. First, the IEEE 14 bus system was simulated using DIgSILENT software in ideal condition.Then, the system loadability was increased up to 200% of initial value to locate the weakest bus. This study includes the applicable location and sizing of STATCOM and ESS towards improving power system stability. The results showed that the application of STATCOM and ESS with the most reliable size can increase the bus voltage (p.u and kV) of IEEE 14 bus system thus improving the power system stability. For recommendation, the power system stability can be improved by installing multiple STATCOM and ESS at other load buses and applying a controller to both STATCOM and ESS to improve the effectiveness of generating and absorbency of active and reactive power in the power system.
