2 Why develop the IADS? Power Resource Generators Wind Solar Interties Battery Banks Electric Vehicles Ice Bears Demand Response Type Supply Supply* Supply* Supply/Demand Supply/Demand Supply/Demand Demand Demand Operators must balance supply and demand to minimize imbalance Optimize dispatch of Generation and Distributed Energy Resources Integrate and leverage renewable resources Wind and solar (*) can t be controlled but can be forecast Supply-side Resources Demand-side Resources Supply/Demand-side Resources

5 What is IADS Integrates Demand and Supply side resources into the day-ahead and real time operation of the electric utility Optimizes and Automates dispatch of resources Generation Renewable energy resources (solar and wind) Energy and ancillary service purchases Demand response Direct load control Load shifting Energy storage Distributed generation, PV, and EV charging systems 5

6 What is IADS (Con t) Develops Most efficient operational scenario: Economic Optimization: Developed while simultaneously considering operational reliability and system security matters System reliability: Determines which scenario is actually placed in service Operates efficiently: Within a coordinated regional market such as the CAISO Core Functionality: Aggregating, base lining and trending of distributed energy resources, end use customer loads (and where authorized how they can be managed) 6

7 What is IADS (Con t) A joint effort between: SAIC acting as Owner s Engineer OATI - Open Access Technologies International webdistribute - Demand-Side Management webdispatch - Coordinated Resource Optimization Telvent/Schneider Electric Power Control System (PCS) Automatic Generation Control (AGC) 7

8 OATI webdistribute webdistribute Functional Components: DR Enrollment and Contract Management DR Program Creation and Administration DR Customer Baseline Load Calculation Aggregation and Virtual Power Plant Creation DR Availability Assessment and Forecasting DR Scheduling and Optimization DR Dispatch and Operations Work Flow Field Interfaces DR Performance Monitoring DR Settlement Measurement and Verification Enterprise Systems and Data Interfaces Wholesale Market Interfaces 8

9 OATI webdispatch Day-Ahead, Day-Of, and Real-Time Schedules for Generation, Demand Response, and Storage Resources Day-Ahead and Day-Of operating modes Produces optimal hourly schedules of Power Resources to meet demand and to assure appropriate levels of system operating reserve Schedules must respect operating constraints such as Power Resource Max/Min capability and Ramp Rate Day-Ahead Time horizon covers the Next hour to up to seven days in one-hour increments Day-Of process time horizon covers the next six hours in one hour increments Produces hourly values of generation for all available generators, hourly trades into/out-of market points (trading or scheduling locations), etc. Real-Time mode Produces five-minute schedules Short-term dispatch to meet demand while minimizing operating costs and interchange imbalances Considers Bilateral Contracts and Market-based Trade opportunities. 9

10 Telvent Power Control System Power Control System Functional Components: Load forecasts for day ahead and hour ahead Variable renewable resource forecasts for day ahead and hour ahead Transfer of load and renewables forecasts to webdistribute Real-time monitoring for insufficient local generation and insufficient demand for minimum generation Generator dispatch in response to base points& participation factors provided by webdistribute Model conventional and combined cycle gas power plants Model renewable generators and energy storage devices Automatic Generation Control (AGC) for generation resources Area Control Error (ACE) measurement and control (CPS1 & CPS2 compliance) Inadvertent interchange energy management 10
