Modernized Grid

Modernized Grid: New Information Systems and Applications

• Utilities collecting more data to manage new technologies

• Utility data traditionally resides in siloed data systems

• Modern grid applications require multiple, diverse data types

• Solving this challenge using a common data integration platform,

called the Renewables Database

• Topics:

• Examples of applications enabled by the Renewables Database

• Integrating information to enable applications

• Value of partnerships

Voltage Control Analysis

Summarize voltage and transformer adjustments (Load Tap Changes) to

maintain voltage:• Identify transformers that are “working” harder than others

• Often due to high solar penetration circuits

• May result in reduced transformer longevity

• If solar penetration increases further, could result in power quality issues

• Monitor situation or take corrective action

Monitoring Independent Power Producers (IPPs)

• Enabled through availability of renewable resource and power production

historical data• Power Purchase Agreements are based on Calculated Output

• Differs from Actual Output if there is a surplus and IPP is curtailed

6

• Computing Calculated Output fora wind farm:

• Use historical data to build

power curve for wind farm

• What was the wind speed?

• Estimate Calculated Outputusing power curve and wind

speed

The Value of Partnerships

• Hawaii-based small business

• Working with MECO and HECO since 2009• HECO partnership has been invaluable

• Domain expert users

• Teaming and introductions

• Important guidance and R&D funding over the years from PacificInternational Center for High Technology Research (PICHTR):

• Matching funds for initial projects at MECO

• Key Energy Excelerator / Department of Energy project helped us

make the jump from Maui to Oahu
