Model Verification

XENDEE uses sophisticated algorithms to identify and help resolve network design issues to ensure reliable simulation outcomes. Real-time field level error checkers and tool-tips help avoid input data errors. Integrated engineering logic and real-time error checkers help eliminate input data & design errors.

Increase Adoption with Trialability

Employing next-generation QSTS Power Flow simulation technology, XENDEE improves confidence and
customer adoption by delivering “trialability” of optimized Microgrid designs with virtual test-drives.

Quasi-Static Time-Series Power Flow

XENDEE’s Microgrid simulator provides the sophisticated features engineers need to model peer-to-peer multi-phase power distribution systems and traditional balanced 3-phase industrial networks.

Novel algorithms powered by EPRI OpenDSS deliver both world-class simulation speed and essentially guarantee power flow solution convergence with a default tolerance of 0.0001 in voltage magnitude.

Real and reactive generation and loads can be scheduled at any location and users can easily examine: bus voltage, power flow of kW and kVAR through cables, wires, circuit breakers and transformers, accurately determine total system losses and line and transformer loading, along with bus voltage and line current violations.

Integrated Geospatial Information System

The XENDEE One-Line and power system simulation model connects with Google Maps Geographical Information System to enable overlay of your power system onto its real geographic location. This enables users to truly visualize the system like never before, while informing system design decisions.

Short Circuit Analysis

With the need to analyze flowing faults within a Microgrids peer-to-peer energy delivery model, a new generation of power system planning and analysis technology is required. XENDEE’s cutting-edge solutions are powered by the Electric Power Research Institute’s simulation technologies and represent the output of over two decades of research and development in Smartgrid and Microgrid analytics. XENDEE provides design engineers with the unique ability to model Microgrids and perform short circuit simulations on interconnected, meshed balanced and unbalanced multi-phase topologies.

  • Analyze faults for Microgrid designs

  • Analyze flowing faults per ANSI/IEEE Red Book

  • Analyze 1/2 cycle, 1.5-4 cycle, 8 cycle and 30 cycle faults in high-fidelity

  • Determine effects of faults at any location applying Classical or ANSI C37 / IEEE

  • Faults for varying time cycles such as Peak, Momentary, 1st Cycle and Interrupting


As machine sub-transient reactance and reactance values adjust per fault cycle, so does network impedance and fault location X/R within XENDEE.

Integrated ANSI C37 / IEEE and Classical calculation algorithms help engineers design Microgrids and complex industrial systems that operate safely and reliably under various operating conditions. Depending on the desired calculation method, Peak, Momentary 1/2 cycle, 1st cycle, 1 1/2 – 4 cycle, interrupting, 8 cycle and 30 cycle faults at any 3-phase, 2-phase or 1-phase location within the power distribution system can be analyzed with granular reporting on current flows (at both terminals of all equipment), powers, angles and voltage.

The flexibility to simulate virtually any fault scenario offers the extensibility needed to best analyze current and future Microgrid designs.

Automated Reporting

Regardless of analysis types, XENDEE allows you to generate professional reports within seconds, and share them via many popular output formats.

  • Data is at your fingertips in an easily readable manner instantly following a power flow simulation.
  • Full length professional reports are automatically generated, which give a detailed and complete overview of the system.
  • Easy to read plots and tables are generated, which can be used directly for presentations/reports, cutting post processing time to a fraction.
  • A number of XENDEE innovative Microgrid-specific metrics, which are becoming the industry standard, make you better informed of crucial technical and economic consequences of your investment.

XENDEE leads the industry in providing a powerful and accurate Microgrid, Minigrid, and Distributed Energy Resources design and implementation tool that optimizes selection, sizing, dispatch, and placement of technologies in addition to power flow analyses.
