Energy and power systems

Photovoltaic and wind characterisation, battery ageing, and the load and generation curves a grid operator plans against. The distinctive plotting need is showing two quantities that share an x axis but nothing else – current and power, capacity and efficiency – and showing composition over time without losing the total.
