Pacific Island Wind Farm24 MW Wind With 11 MW/4.4 mWh Battery Energy Storage

Great Valley Solar Battery-Ready 200 MW Solar Facility

Great Valley Solar (GVS) includes four independent

solar sites with five separate SCADA licenses that tie

into a common point of interconnection (POI). The SCADA system for the sites controls eighty-two 2,500 kW inverters.

OpportunityGVS was unable to meet its full power supply and

earning potential due to a risk of circular Var flow

from site to site.

The site consists of eight 3 MW wind turbines with an

11 MW BESS and nine 1.22 MW Dynapower inverters.

OpportunityThe original control solution for this site consisted of

PLCs and SCADA with limited battery ramp control

for the variable wind output. High levels of variable

generation on the island and limited control capabilities

resulted in periodic wind curtailment.

SolutionThe PXiSE Power Plant Control solution provides real-

time feedback control of both active and reactive power

which improved site economics. The control solution

also integrates controls across the four sites for efficient

operations and is battery storage ready. The solution

includes an embedded OEM version of the OSISoft PI

data platform.

SolutionPXiSE deployed its Power Plant Control solution to autonomously coordinate the BESS for effective

frequency and Volt/Var control. PXiSE held frequency constant at 60 Hz in dynamic grid conditions and

demonstrated the ability to reduce thermal generation,

thereby producing cost savings.
