i want matlab simulink model of 9 bus system

matlab code for ieee 39 bos

The IEEE 39 New England Power Grid Model consists of 39 buses and 10 generators. Generator 10 is an equivalent aggregated model for the part of the network that we do not have control over; generators 1 to 9 are equipped with Power System Stabilizers (PSSs), which provide good damping of local modes and stabilize otherwise unstable open-loop system. We use a sparsity-promoting optimal control strategy to design a supplementary wide area control signal aimed at achieving a desirable trade-off between damping of the inter-area oscillations and communication requirements in the distributed controller. Inter-area oscillations are associated with the dynamics of power transfers and they are characterized by groups of coherent machines that swing relative to each other. These oscillations are caused by weakly damped modes of the linearized swing equations and they physically correspond to active power transfer between different generator groups.
