POUNAMU forms a component of the ZERO project which aims to develop platform of tools to plan the transition of New Zealand to a zero-carbon economy by 2050. The aim of POUNAMU is to optimize the deployment of short-term storage devices to deal with intermittent energy supply from renewables (wind, solar and run-of-river hydro). POUNAMU will be based a short-term electricity optimization model that will be solved using sddp.jl (for convex problems) or JuDAS.jl (for non convex problems).

JADE is an infinite-horizon SDDP model for the New Zealand electricity system. This project will extend an existing single reservoir model (written in Julia and based on sddp.jl) to a multi-reservoir framework incorporating transmission losses and constraints. The new software will admit models with different levels of risk aversion applied to inflows as well as aother factors such as demand and fuel costs. The project will also investigate a distributionally robust version of SDDP applied in this setting.

EMERALD is a Julia package for optimizing long-term capacity investment for 100% renewable electricity systems. It is based on JuDGE.jl, which minimizes the expected cost of meeting uncertain demand over a long time horizon, using a Dantzig-Wolfe decomposition algorithm. The time horizons are many years, and so modelling risk is important. This project will develop an approach to incorporate risk aversion into EMERALD.
