Nature Inspired Optimization Algorithms for Power System

A power system is said to maintain its voltage stability, if it delivers power within acceptable voltage levels, under normal working even after being subjected to a disturbance. However, in the event of the stability cannot be maintained, then the system voltage levels decay irretrievably, causing immense harm to the economy, because of the resulting outages. Hence it is imperative that the voltage stability analysis is carried out to obtain the maximum loading point on the system without resulting in a voltage collapse. As the power loading increases, so do the real power losses, thus it becomes significant to optimize voltage stability limit (VSL) along with RPL. This aim is reached through the application of OPF and CPF methods for optimization. The RPL and VSL are like a see-saw, in the sense that optimizing one, deteriorates the other. Hence finding a mutually optimal solution is crucial for the power system operation.
