Time Domain Power Flow

Time Series Unified Load Flow

Time Series Unsymmetrical Network Unified AC & DC Load Flow

Time domain unbalanced power flow or time series distribution load flow simulation is used for the purpose of varying load and generation in the system and solving the steady state power flows in the system over a function of time.

Key Features

Single year load growth analysis
Multiple year load growth analysis
Live one-line diagram plots for graphical results comparison and analysis
Progress bar with elapsed and remaining time

Capabilities

Consider unlimited loading and generation patterns using ETAP Profile Library
Allows specifying user-defined intervals for the profiles (hours or minutes resolution)
Supports the import of profiles from ASCII format (.csv)
Simplifies the creation of profiles for standard profile types such as the "8760 profile";
Define seasonal variations including holiday adjustments
Include load growth for multiple years (unlimited)
Ability to mix customer classes or sectors into composite sectors
Include solar irradiance patterns to simulate daily, monthly or yearly output from PV modules
Graphically assign customer classes or sectors to loads and generators
Automatic time series synchronization of multiple patterns
Ability to include devices in service or place them out of service during the planning period
Time series plot comparison & evaluation include: current, voltage drop, energy losses, demand, yield, and consumption for a specified period
Provides the functionality for creating, viewing, and editing profiles for a specific customer, or by customer type, meter demand, network demand, or generator graphically or tabular view
