Unlike other OPF modeling frameworks, ExaModelsPower.jl leverages the capabilities of <a href="https://exanauts.github.io/ExaModels.jl/stable/">ExaModels.jl</a> in order to solve more complex, large-scale versions of the OPF. ExaModels.jl employs what we call <a href="https://en.wikipedia.org/wiki/Single_instruction,_multiple_data">SIMD</a> abstraction for <a href="https://en.wikipedia.org/wiki/Nonlinear_programming">nonlinear programs</a> (NLPs), which allows for the preservation of the parallelizable structure within the model equations, facilitating efficient <a href="https://en.wikipedia.org/wiki/Automatic_differentiation">automatic differentiation</a> either on the single-thread CPUs, multi-threaded CPUs, as well as <a href="https://en.wikipedia.org/wiki/Graphics_processing_unit">GPU accelerators</a>. More details about SIMD abstraction can be found <a href="https://exanauts.github.io/ExaModels.jl/v0.8/simd/">here</a>. ExaModels.jl compiles (via Julia's compiler) derivative evaluation codes tailored to each computation pattern. Through reverse-mode automatic differentiation using these tailored codes, ExaModels.jl achieves significantly faster derivative evaluation speeds, even when using CPU.</p><p>Recent benchmark results demonstrate that derivative evaluation using ExaModels.jl on GPU can be up to two orders of magnitude faster compared to JuMP or AMPL [<a href="../ref/#shin2024scalablemultiperiodacoptimal">1</a>]. This enables us to implement more complex versions of the OPF without needing any relaxations. Currently, ExaModelsPower.jl supports developing models for static OPF, multi-period OPF with or without storage, and security constrained OPF. ExaModelsPower.jl also supports a number of flexible options for the user to specify model coordinate system, setup of time-varying demand profiles, and handling of complementarity constraints for storage models. </p><h2 id="Supported-Solvers"><a class="docs-heading-anchor" href="#Supported-Solvers">Supported Solvers</a><a id="Supported-Solvers-1"></a><a class="docs-heading-anchor-permalink" href="#Supported-Solvers" title="Permalink"></a></h2><p>ExaModelsPower can be used with any solver that can handle <code>NLPModel</code> data type, but several callbacks are not currently implemented, and cause some errors.
