Introduction

  • Analytical approach to get the most out of technology investments.

  • Benefits:

    • Determine the best technologies, where they should be deployed, and to what degree.

    • Recognize the driving factors and changes that makes these the best solutions.

    • Defendable plan of action (project benefits are based on detailed analytics).

Optimized Spend


Model Overview

  • TIP can be updated as the system changes or solution costs change.

  • All input data, algorithms, and assumptions will be provided in a user friendly benefit cost model.


Data Flow


Project Approach

  • Data Collection– Coordinated effort to define technologies, feeder & system characteristics, and financial assumptions.

  • Algorithms Development – DNV GL has tools and previous project experience relating feeder characteristics and solution benefits.

  • TIP Model Customization - Define global and project specific variables, incorporate algorithms.

  • Optimal Plan – Recommended plans based on various levels of spend and focus areas.


Algorithms Development

  • Algorithms relate detailed project drivers to program benefits.

  • Illustrate the amount of equipment deployed and benefit / costs associated with roll-out.

  • This approach results in a robust benefits and costs assessment.

Detailed System Models and Benefits

Detailed Metrics on a Feeder Basis


Optimal Plan

  • Findings will illustrate optimal solutions under various conditions:

    • Cash Flows.

    • Diminishing returns.

    • Detailed feeder results.

    • Combined projects (projects will interact and provide synergy).

    • Time varying factors (load growth, renewables, electric vehicles etc.).


Features

  • Provides a list of recommended feeders and technologies applied on a benefit cost basis.

  • Optimal spend curve shows the value for a given level of spend.

  • Allows project solutions to be shown individually or combined.

  • Uses utility data to provide a customized solution.

  • Output is easy to understand and use in decision making.

  • Assumptions can be changed to understand the sensitivity to the utility environment.

  • Provides detailed output that is available when needed but summarized if not.

  • Provides a tried and tested approach. Successfully deployed with other utilities.

Filtering - Turn technology on and off to see the interactions, investigate solutions, combined benefits and costs.


Example

Find the top 3% of feeders in terms of benefit to cost for fault current indicators, assuming they are distributed equally along the feeders.

Applied Filters

Tabular and Graphical Results


Findings

  • Each utilities' financial, operating and regulatory environment is unique; however, there are several common themes.

  • The following are high-level lessons learned from smart grid solutions benefit cost modeling projects with utilities:

    • A majority of the benefits are achieved by applying technology to a subset of the system (i.e. the top 10% of feeders may account for 50% of the possible benefits, similar to the 80/20 rule).

    • Dispersing project solutions is more effective than lumping them (e.g. it is better to place fault current indicators on the top 10% lightly than the top 5% more densely).

    • Combined solutions are more attractive (e.g. there are often synergies between solutions, communications costs are shared between projects).

    • Changes in company priorities and financial parameters have a big impact on results (e.g. changes in future needs alters project outlook, it is important to look forward and understand variability and trends).
