How does the digital twin handle sudden outages or unplanned events, and what data sources feed into the investment optimizer for BESS recommendations?
@arifevrec For the sudden outages, it models the NEM as a live graph with a bus admittance matrix. On a trip or failure, it zeroes out that line's admittance or the generator's output, then re-solves the dispatch (DC-OPF via HiGHS) across the remaining network. LMPs come straight from the Lagrange multipliers on the power balance constraint — so congestion from the outage shows up as an immediate, localized price spike.
and for the BESS, it combines live AEMO load/price/curtailment data, network contingency exposure, and weather forecasts (wind/solar) to jointly size power and energy capacity, factoring in round-trip efficiency and a 5-year degradation model.
How does the BESS investment optimizer actually model revenue stacking across FCAS, energy arbitrage, and spot exposure at the same time?
@ceylin1791609 The battery can't do everything at once — physically, whatever power it's using to trade energy eats into what's left for FCAS, so the model always keeps that headroom in check. It plays spot price spikes first: if prices go extreme (dirt cheap or sky-high), it charges or discharges at full power because that's where the real money is. Only when prices are sitting in a normal range does it switch to bidding into FCAS, and even then it holds back to half the battery's capacity, since FCAS needs a fast, reliable response and you don't want to overcommit.
The whole time, it's tracking the battery's charge level in real time, factoring in that batteries lose a bit of energy in the process (~90% efficient). If the battery's about to hit empty or full, it automatically pulls back any bids so it's never promising power it can't actually deliver.
The digital twin visualization looks incredibly clean, especially the way the flow animations layer over the grid map without cluttering the data readouts. Whoever designed that balance between density and clarity clearly knows their audience.
