Bus Model

A bus is a point of interconnection of electrical devices. Bus component model also plays a key role in coupling system components. Each bus \(k\) owns two variables – real and imaginary voltage \(V_{rk}\) and \(V_{ik}\), respectively. The bus also owns current balance residual equations for real and imaginary currents coming into the bus \(I_{rk}\) and \(I_{ik}\), respectively. While th bus model owns current residuals, it does not compute them. Instead, each component connected to the bus is adding its contribution to the residual. The bus will merely initialize the residual to zero each time numerical integrator requests residual evaluation.

Sign Convention

Current entering the bus has positive and current exiting the bus negative sign.

Other Parameters Buses are uniquely defined by their ID (number or name). Besides, each bus should have associated Nominal Voltage value.
