This branch focusses on the implementation of a State Space Nodal (SSN) simulation approach for real time analysis within the EMT domain limited to linear components. The approach is based on the paper “A Combined State-Space Nodal Method for the Simulation of Power System Transients” ,doi: 10.1109/TPWRD.2010.2090364 of Dufour et al. .
Linear State Space Nodal models of basic components and linear circuits like an RLC circuit are implemented as single SSN components. To achieve this a state space representation for the electrical element or circuit is derived. Those equations are discretized using the trapezoidal rule of integration. The system of linear equations is manipulated such that current states in the output equations of the state space model can be replaced with known terms, i.e. state values of the previous simulation step and input quantities. Previous states are additionally stored within the SSN component and updated when the system has been solved for the current time step. Now the output equations (nodal equations for V-Type SSN-Groups, mesh equations for I-Type SSN-Groups) can be used in the Modified Nodal Analysis approach by the already implemented stamping and task systems.
Because of that the simulation sequence and structure does not have to be changed for these components, only the used methods itself differ in the executed calculations and the quantity updates for the internally stored states.
Regarding general changes not limited to the SSN approach, a setter method (setParameters) has been added for the Ph3::CurrentSource. Furthermore, a Ph1::Switch was added together with a validation example testing the new component. Ph1::Switch, Ph1::CurrentSource and Ph3::CurrentSource were made usable within the pybind python module.
