State Estimation, Power Flow, Contingency Analysis, Fault Analysis• Determine the current operating state of distribution grids using AMI and/or SCADA

data and discover and eliminate data/topology errors

• Calculate and display severity and worst system loading and voltage contingency violations based on modeling of outages on conductors and transformers, generate alerts, calculate fault level

Analysis of DR, DG, DER, EV, Microgrids, Improved Customer Service• Evaluate the current and near-term energy and economic state of distribution grids

including demand response (DR), distributed generation (DG - solar and wind, including smart inverters), distributed energy resources (DER - energy storage), electric vehicle (EV) charging stations, microgrids, Volt/VAR Optimization (VVO), and Grid Interconnection programs, improving customer service

Load Profiling, Short-Term, and Long-Term Load and DER Forecasting• Create load profiles, develop short-term (days ahead) and long-term (months to years

ahead) energy and economic forecasts including DR, DG, DER, EV, and microgrids

• Generate alerts and dispatch resources based on forecast conditions

Management of Independent Grids and Microgrids, Reliability Coordination/Market Operations

• Manage independently owned commercial and industrial grids and microgrids

• Coordinated capacity calculation and security analysis, outage planning coordination, short-term and medium-term adequacy forecasts

Advanced Data Quality and Reliability Analytics• Analyze and improve transformer to meter assignment, phase assignment, sizing of

devices and conductors, asset health indexes, energy theft, prior outage causes and future outage prediction, and other data quality and operational factors based on AMI and/or SCADA data and distribution network models

Manage the solar/storage/EV/DR interconnection process • Public User Interface• Engineering Studies• Contracting• Construction• Financial Settlement/Closeout

1. Customer requests adding solar/storage/EV/DR at a existing or new location in iEnergy

2. Grid360 DA calculates hosting capacity (existing + queued+ forecasted load and generation + reserve capacity) and impacts on loading percentage, voltage, and unbalance

3. iEnergy presents results to the customer and is used to continue the interconnection process
