Usage of Interlinks in an Electrical Distribution System-----A Boon in Reducing Reactive Power Requirement at the Load Bus
Abstract:-It is observed that one of the reasons for voltage instability is voltage collapse. Generally, the concept of reactive power management is used to mitigate voltage collapse. But in this work, the following novel concept is used. The mathematical derivations begin from the usage of the conventional voltage collapse indicators(VCPI) Interlinks are used in the power system to distribute real powers locally (Inter bus power transfer) to mitigate voltage collapse. Optimal assignment of Distributed generation capacities are found out at different buses to mitigate voltage collapse. A mathematical model is derived and this model helps to design a valid algorithm to take care of voltage collapse problems. The Implementation of the algorithm is done through a MATLAB program which is shown in the Appendix. But minimum reactive power is to be maintained in the system.
Quadratic Programming is applied in the fields of Control and Communications [13], Optimizing the civil structural design[14], nonlinear programming applications are presented that have arisen in different industries, namely food and insurance[15], Economics portfolio selection, monopolists' profit maximization, inequality constrained least-squares estimation, spatial equilibrium analysis, goal programming with quadratic preferences, and optimal decision rules [16] , But in this work Quadratic Programming is applied to find a way to mitigate voltage collapse in a power system.
