Hydropower generates about seven per cent of the energy in the National Electricity Market (NEM), but about 85 per cent of the energy in Tasmania. Historically, many NEM modellers have used simplistic representations of hydropower. However, as more variable renewable energy enters our system, the firming role of hydropower and other storage technologies becomes more important. Additionally, the impact of the proposed Marinus Link (additional interconnection between Tasmania and Victoria) will increase the interplay between hydropower and other NEM resources.
Modelling hydropower is complex compared to other energy sources due to the deep interdependence between operating decisions at different points in time, as well as the interdependence between different hydropower stations along the same river (or cascade). This presentation will consider the factors required to accurately model hydropower operation in the NEM, and introduce some of the common modelling techniques. Many of these lessons are transferrable to emerging storage technologies.
