Since Loop 7 has the capacity to serve all load demands with a controllable power plant, power flow calculation of this loop is shown in island mode. 46 Three-phase voltages Three-phase power flows
Day-Ahead Optimal Scheduling • This figure shows the data flow for the day-ahead optimal scheduling in ICMMC. • The day-ahead market clearing price from ComEd would be used as the forecasted electricity price and the forecasted fuel price would be applied. • The solar unit generation would be calculated based on the seasonal generation profile combing with the sunrise/sunset time and forecasted cloudy information. 48 UC/ED (day-ahead) Forecasted load based on historical load data Forecasted fuel price in market Day-ahead Electricity Price from ISO Solar Generation calculated based on seasonal profile, sunrise, sunset and cloudy information Microgrid Component Status (In Service or not) Demand Response Signal Hourly Grid Dispatch and Cost Hourly Co-gen Dispatch and Cost Hourly Battery Charging/ Discharging Status Hourly Load Curtailment Hourly Voltages and Power Flow • The load would be predicted using linear regression method based on historical load data. • With all the forecasted information and forecasted microgrid component status, the set points for controllable generation resources (co-gen and battery) would be calculated as reference set points.
Real-Time Optimal Scheduling • This figure shows the data flow for the real-time UC/ED in ICMMC. • The available generation capacity would be calculated based on the current system operating point (co-gen and battery). 49 UC/ED (real-time) Last measurement of loads Forecasted fuel price in market Real-Time Electricity Price from ISO Last measurement of Solar Generation Microgrid Component Status from OSISoft PI System Current microgrid operating point Grid Dispatch and Cost Co-gen Setpoint and Cost Battery Charging/ Discharging Setpoint Load Curtailment/ Switch Setpoint Voltages and Power Flow • The objective function
