Vectorised Schedule, Pricing and Dispatch (vSPD) is a version of the Schedule, Pricing and Dispatch (SPD) market clearing engine used in the New Zealand electricity market. It is developed using the General Algebraic Modelling System (GAMS) and is based on the SPD formulation.
vSPD takes advantage of the computational efficiency of some current LP solvers through vectorisation of some schedule solves. This vectorisation involves reformulating the sequential trading period problems as a single optimisation problem which requires a single LP solve for the whole schedule.
The data inputs into vSPD are in GDX (GAMS data exchange) format.
vSPD reports on generation, load, prices, branch flows and reserves.
vSPD with an Excel interface is available for download. See the Downloads page.
