 Prototype Building Electrical Models
 ====================================
 
-The **Prototype Building Electrical Models** are detailed electrical distribution system models designed to accompany the [Prototype Building Models] maintained by the U.S. Department of Energy (DOE)) [Building Energy Codes Program]. The electrical distribution models are implemented using [BEEAM], a [Modelica] library that simulates the performance of building electrical distribution systems using harmonic power flow.

-The prototype building electrical models are intended to support simulation-based research of building electrical distribution system efficiency and harmonic performance; comparison of alternating current (AC) and direct current (DC) electrical system designs; and grid-interactive, efficient buildings (GEBs). Each model consists of a realistic electrical distribution system design implemented in Modelica, including distribution equipment (*e.g.* transformers, cables), power electronics converters (including load-packaged converters), local photovoltaic (PV) generation (if applicable) and individual loads. At present, the models focus on granular representation of lighting and miscellaneous electrical loads (MELs).

 The following distribution topologies are represented:
 
-- Conventional AC distribution: representative of typical design practice
-- Local DC distribution: low-voltage lighting and MELs served by common AC/DC converters (*e.g.* PoE switches or 24V multichannel converters)
-- Central DC distribution: central 380 V DC backbone with low-voltage lighting and MELs served by step-down DC/DC converters
