![]() ![]() ![]() The advantages of this algorithm over traditional finite difference-based simulators are: 1) it handles unusual situations much more accurately 2) it handles widely disparate time scales, ranging from sub-seconds to many years and 3) it is very easy to integrate with new modules and third-party systems.Īt its simplest, GridLAB-D™ examines in detail the interplay of every part of a distribution system with every other. ![]() The core of GridLAB-D™ has an advanced algorithm that simultaneously coordinates the state of millions of independent devices, each of which is described by multiple differential equations. GridLAB-D™ is a flexible simulation environment that can be integrated with a variety of third-party data management and analysis tools. Version 4.0 for Win32, Win64, and several 32/64 bit Linux/MacOS implementations was released in September 2017. Department of Energy (DOE) at Pacific Northwest National Laboratory (PNNL) under funding for Office of Electricity in collaboration with industry and academia. GridLAB-D™ is coupled with distribution automation models and software integration tools for users of many power system analysis tools. ![]() It incorporates the most advanced modeling techniques, with high-performance algorithms to deliver the best in end-use modeling. GridLAB-D™ is a new power distribution system simulation and analysis tool that provides valuable information to users who design and operate distribution systems, and to utilities that wish to take advantage of the latest energy technologies. This allows you to see the impact of variables that are beyond your control, such as wind speed, fuel costs, etc, and understand how the optimal system changes with these variations.Questions or comments about the website please email the GridLAB-D™ Webmaster HOMER makes it easy to compare thousands of possibilities in a single run. HOMER lets you ask as many “What if?” questions as you’d like, because you cannot control all aspects of a system, and you cannot know the importance of a particular variable or option without running hundreds or thousands of simulations and comparing the results. HOMER Optimizer™ is a proprietary “derivative free” optimization algorithm that was designed specifically to work in HOMER. HOMER Pro features our new optimization algorithm that significantly simplifies the design process for identifying least-cost options for microgrids or other distributed generation electrical power systems. HOMER examines all possible combinations of system types in a single run, and then sorts the systems according to the optimization variable of choice. HOMER simulates the operation of a hybrid microgrid for an entire year, in time steps from one minute to one hour. Depending on how you set up your problem, HOMER may simulate hundreds or even thousands of systems. It will attempt to simulate a viable system for all possible combinations of the equipment that you wish to consider. Originally developed at the National Renewable Energy Laboratory, and enhanced and distributed by HOMER Energy, HOMER (Hybrid Optimization Model for Multiple Energy Resources) nests three powerful tools in one software product, so that engineering and economics work side by side:Īt its core, HOMER is a simulation model. The HOMER Pro® microgrid software by HOMER Energy is the global standard for optimizing microgrid design in all sectors, from village power and island utilities to grid-connected campuses and military bases. ![]()
