    ...electricity markets. In addition to deciding which market, or combination of markets, to participate in, they also need to decide what quantities of energy (and when) to buy and sell. This is becoming increasingly difficult given price volatility in wholesale electricity markets (which is in part influenced by the build out of variable renewable generation assets). In this project, I will consider a hypothetical battery which will operate solely in the day ahead market (i.e. we focus on a particular optimisation problem in the overall domain). Then, following similar or alternative approaches to those outlined in the reference material below, we have to derive both “perfect foresight” and “imperfect foresight” estimates of the storage value o...

Separate types of motorcycle battery each local manufacturer sells, example: lead acid battery, lithium ion, copper, nickel, cobalt, dry etc. D. Incase selling prices are available, please mention. (I think prices will not be easy to find because rates keep changing. So don’t focus much on this point. Incase readily available on manufacturers website that is okay. Otherwise no need)
