BSI and Hitachi have joined forces to produce the Optimized Performance Enabling Network for Volt/Var (Q) platform (otherwise known as OPEN V-Q) that will forecast future power system conditions and optimize the voltage profile using AC-Optimal Power Flow (ACOPF) technology and online data. The goal is to bring “innovation in power grid operation by online optimization technology”.
The OPEN V-Q Platform seeks to:
Tokyo Electric Power Company (TEPCO) – Power provider for Tokyo (Japan) and the surrounding region, and the largest investor-owned utility.
The OPEN V-Q Platform simulation on the TEPCO Power Grid
Hitachi Ltd. and Bigwood Systems, Inc. teamed up with Tokyo Electric Power (TEPCO), Ernst & Young, and the Electricity Generating Authority of Thailand (EGAT) for a feasibility study on the northeastern area of the Thailand power grid.
In addition to OPEN V-Q, BSI offers RPCT for volt-var optimization, specifically to predict and remove future grid violations (voltage and thermal) through coordinated reactive power scheduling using optimal static and dynamic control options.
The RPCT integrated package is used in both on-line (near real-time) and off-line study modes. The coordinated reactive power scheduling is conducted through static and dynamic control options to mitigate expected hourly violations over a future time duration (12 hours to start but extended to 48 hours ahead of real time). The powerful engine behind RPCT prioritizes various control types, constraints (temporal, physical, reactive reserve, etc.), and user configurations to find the best and most efficient solutions. This means for a given time duration, the RPC tool will provide optimal control recommendations that will handle violations for several hours at once with minimal control adjustments.
This innovative tool is different from traditional segregated Volt/VAr tools and other look-up table control tools, which degrade overall performance due to changes in system configuration, renewable uncertainties, varying load profiles, etc. RPCT uses the most up-to-date information to make system condition calculations on-the-fly.
