Main functions provided by business logic（1/3）
Forecast•••

Because the controllable amount of resources affects the profit of the aggregator, it is important
to improve the forecast accuracy. Our AI-based forecast engine predicts demand, PV power
generation, storage battery and EV SoC through external APIs such as weather forecast, anddelivers the forecast data to business logic.
Our Forecast Engine is a tool to automatically perform forecasts, based on time series, using machinelearning algorithms and deep learning. This algorithm trains a forecasting model, handling outlier andmissing data set.
Our forecast engine provides a two day forecast with intervals required by customers of the series(i.e. 30min interval).

Optimization••

Based on the resources’ performance data and the forecast data supplied by the forecast engine, ourAI-based Optimization Engine generates a Demand & Supply. In doing so, the Optimization Engine
can autonomously create control instructions for the resources independent of the control
instructions from the TSO.
Based on Demand & Supply Forecast value, our Optimization Engine will create a 24-hour (48frames) demand & supply plan. The schedule is updated every 30 minutes as the forecast isupdated.

Event Management / Distribution•••

It is a function to distribute control commands to consumer resources that can be controlled according
to the schedule created by the optimization engine.
After creating the control instruction, it responds through the following sequence.
1) (For DR) Calculate the baseline based on the control performance (power usage) of resources.
2) Judge whether to participate in the event from the distribution result, and return a response to VEN.
3) (For Non-DR) Check the supply-demand imbalance every 30 minutes, and if imbalance occurs,
return a response to the optimization engine, and the optimization engine recreates the demandsupply plan.
You can also check the success rate judgment for each event on the GUI.

Performance Management•••

It is a function to acquire and manage the actual information from resources and a function to send it tothe power transmission and distribution business operator. It is also used as information for optimal
distribution of control instructions in conjunction with the forecast engine.
Performance management is mainly 1) "Resource performance registration", 2) "Resource performanceaggregation", 3) “Send Report"：
1) "Resource performance registration“: Receive performance from each resource and register themin the database.
2) "Resource achievement aggregation“: resource performance aggregation request (schedule base)is received and the performance is sent to VEN.
3) "Send report“: sends the aggregated resource results to VEN.
Supports three reports: "baseline report", "control performance report", and "controllable amount report".

Baseline Calculation••

The baseline is an estimate of the amount of power demand without demand restraint. The amount ofdemand restraint at the DR event. It is calculated as the difference between this baseline and the actual
power demand.
Business logic calculates the baseline based on the results aggregated from each resource, and uses
the averaging method (High 4 of 5: data for the 4 days with the highest power consumption in the last 5days).

System Configuration••

It is a function to manage the load information of the resources owned by each consumer, the baseline,
and other information about the consumer.
You can also check the success rate judgment of the response for each resource on the GUI.
