Test Cases

Directory

ANDES comes with several test cases in the andes/cases/ folder. Currently, the Kundur's 2-area system, IEEE 14-bus system, NPCC 140-bus system, and the WECC 179-bus system has been verified against DSATools TSAT.

The test case library will continue to build as more models get implemented.

A tree view of the test directory is as follows.

MATPOWER Cases

MATPOWER cases has been tested in ANDES for power flow calculation. All following cases are calculated with the provided initial values using the full Newton-Raphson iterative approach.

The numerical library used for sparse matrix factorization is KLU. In addition, Jacobians are updated in place spmatrix.ipadd. Computations are performed on macOS 10.15.4 with i9-9980H, 16 GB 2400 MHz DDR4, running ANDES 0.9.1, CVXOPT 1.2.4 and NumPy 1.18.1.

The statistics of convergence, number of iterations, and solution time (including equation evaluation, Jacobian, and factorization time) are reported in the following table. The computation time may vary depending on operating system and hardware.
