Kumar, Katikala Hem (2015) Contingency Constrained Economic Load Dispatch Using Particle Swarm Optimization For Security Enhancement. MTech thesis.
Power system security plays a very vital role along with the transmission capability. The power system security is mostly influenced by several contingencies. The mean of contingency is any outage of transmission line, outage of transformer, outage of generator etc. from the system. Under contingency the system might get into insecure. Determination of system state that is whether the system is working under secure condition or not that can be deal by security analysis. Insecure of the system means all the components in the system are operating out of the specified limits. If the present operating condition is found that system is not in secure condition then the remedy must be taken to protect the system from the violation of specified limits of particular components under contingency. During the contingency the transmission line power flows will get affected and it might cross the maximum power flow limit. So we have to control the power flows in the transmission lines during the contingency. The power flows in the transmission line can be control by rescheduling of the generators in the system. In this work the particle swarm optimization technique has been utilised to reschedule the generators for getting optimum cost. While rescheduling the generators under contingency the power flows in the transmission line will get control and they will come within the specified limits and security will get enhance under contingency.
