Run scattered resources as one power plant
Based on the Korean virtual power plant (VPP) standard KSGA-025-19, one platform covers everything from plant data collection and control to links with KEPCO and the Korea Power Exchange.
Real screen — VPP dashboard
Real ENERBOT screen (Korean UI) · development test environment with simulator values · plant names and addresses hidden
What the VPP operator system does
Organised along the functional areas defined in Part 1 of the standard (KSGA-025-19-1).
Forecasts tomorrow’s solar output hour by hour from KMA weather forecasts, and scores the error every day.
Builds day-ahead and real-time plans automatically from PV forecasts and ESS state of charge.
Sends each plant its targets according to the plan and utility orders — with on-site protection first.
SMP, forecast-scheme settlement and plan-vs-actual. Statement reconciliation comes with the first contract.
Polls distribution curtailment orders every minute, follows them and records whether we did.
Where each scheme stands
| Scheme | What | ENERBOT |
|---|---|---|
| KEPCO DSO link | VPP registration · day-ahead bids · curtailment orders · metering reports | Built · preparing grid tests Per Part 2 of the standard (KSGA-025-19-2) |
| Exchange forecasting scheme | Day-before forecasts at 10:00 and 17:00 · error-based settlement | In operation Forecasts, submitted values and settlement calculation · exchange submission link after the spec is issued |
| Exchange demand response (DR) | «Use less» on instruction · «use more» when renewables are in surplus (Plus DR) | Planned Fits heat pumps and customer ESS |
| Exchange dispatch (semi-central · RE bidding) | PV and wind output follows dispatch instructions | In development |
Trading and settlement — where the money comes from
Each scheme pays differently. ENERBOT calculates by the published rules and lines up plans and actuals on the same screen.
Checks every hour whether the bid plan was followed and records, order by order, whether we complied.
Sorts each hour into its settlement band per Appendix 2 of the Market Rules and estimates the payment.
Takes the next-day SMP published by the exchange for the «estimated sales» in plans and actuals.
Times per the utility link standard (KSGA-025-19-2), Chapter 14 of the Market Rules and public SMP
Even with several operators
Each operator has its own utility codes, keys, portfolios and screens. A plant can join several schemes at once and is registered separately for each.
The on-site EMS underneath
Even when a VPP order arrives, battery, fire and climate protection is decided on site first — on the same EMS that has protected 198 plants.
