4 SOlUtIOnS In ActIOn SOlUtIOnS In ActIOn ScADA and Remote Supervisory control for Solar Farm challenge: Sophisticated grid-support functionality with remote supervisory communications required for island grid. Remote Hawaiian Electric Co (HECO) SCADA interface Closed loop controls including high speed voltage control, curtailment and ramp rate Solution: AlsoEnergy turnkey SCADA solution integrated with Schweitzer RTAC based Power Plant Controller PowerManager 2000 from AlsoEnergy provides local SCADA server solution. AlsoEnergy configured the Schweitzer RTAC Power Plant Controller to provide control functionality, data concentration, and HECO DNP3 communications interface. High speed (~2 second) closed loop voltage control enables adjustable plant reactive power output to meet HECO voltage setpoint at the Point of Interconnect Closed loop curtailment control Ramp control and power fluctuation rate analysis AlsoEnergy supported successful site acceptance test from HECO HQ office with remote voltage, curtailment and ramp setpoint changes. Benefits of Standardizing on Powertrack Platform challenge: Standardize on a single monitoring provider to expedite O&M workflow and diminish asset management workload. Solution: AlsoEnergy utilizes API and custom software configurations to create seamless integration with client business systems. Ahana Renewables was looking for ways to save time and money on asset management activities for a 59 system portfolio totaling over 45 MW of production. Administrative tasks such as accounting, agency reporting, and performance guarantees were scattered among a host of software programs. AlsoEnergy won a competitive bidding process, and worked with Ahana to migrate the full portfolio to the PowerTrack platform in about 18 months. One year later, an internal audit by Ahana revealed an annual savings of 1,000 work-hours using AlsoEnergy software. (This survey covered data gathering and accounting activities only; this calculation does not reflect other savings due to greater operational efficiencies, etc.) Rincon 1: ScADA Solution for 18MW System Monitoring for large String Inverter Jobs Post commissioning, AES received an exemption from Southern Company for voltage schedule requirements. challenge: Southern Balancing Authority requires Rincon Solar 1 follow voltage schedules per bulk power operations procedure # BPO-1. Solution: AlsoEnergy PowerManager 2000 SCADA system provides closed loop voltage control solution. The Rincon 1 solar power plant is owned and operated by AES Distributed Energy. The project plan required that the Rincon solar plant follow voltage schedules from Southern Balancing Authority per bulk power operations procedure # BPO-1. AES would receive GenComm requests from the Southern Balancing Authority and remotely adjust the voltage set point schedule. AlsoEnergy delivered the SCADA system for Rincon 1 in a tight time window, enabling all project partners to meet their project deadlines. Since AES has other systems on the PowerTrack software platform, they are able to incorporate Rincon Solar 1 into various portfolio-level displays and reports. This reduces asset management workload for AES and contributes to efficient office workflow. challenge: Design a monitoring solution to manage huge data sets from large string inverter systems. Solution: Custom PowerTrack development creates mapped data displays and meaningful performance alerts. GCL New Energy, Inc owns and operates 8 solar farms in North Carolina, totalling over 83 MWDC of production. GCL has implemented a string inverter system from Huawei for these solar farms. The combined systems utilize 2,467 Huawei string inverters. AlsoEnergy performed custom development with Huawei in order to capture and display direct data from their string inverters. AlsoEnergy performed advanced custom configurations to create dashboard displays and alerts personalized for O&M providers and for portfolio asset managers.
