<div class="mw-heading mw-heading2"><h2 id="History">History</h2></div>
<p>The first software program for power engineering was created by the end of the 1960s for the purpose of monitoring <a href="Power_plant" class="mw-redirect" title="Power plant">power plants</a>. In the following decades, Power engineering and Computer technologies developed very fast. Software programs were created to collect data for power plants.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> One of the first computer languages used in <a href="Nuclear_plant" class="mw-redirect" title="Nuclear plant">Nuclear plants</a> and <a href="Thermal_plant" class="mw-redirect" title="Thermal plant">Thermal plants</a> was <a href="C_(programming_language)" title="C (programming language)">C (programming language)</a>. The first power systems analysis program to feature a graphical user interface and <a rel="nofollow" class="external text" href="https://www.ipsa-power.com/">IPSA</a> was designed in the mid-1970s.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> Other platforms for electrical power modelling were created by the end of the 1980s. Currently, the programming language <a href="Python_(programming_language)" title="Python (programming language)">Python</a>, commonly used in French <a href="Nuclear_plant" class="mw-redirect" title="Nuclear plant">Nuclear plants</a>, is used to write energy-efficient algorithms and software programs.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup>

<p>The early 2000s saw the rapid development of analytical programming and <a href="3D_modeling" title="3D modeling">3D modeling</a>. Software products were being created for designing <a href="Nuclear_power_plant" title="Nuclear power plant">power plants</a> and their elements and connections. The programs were based on mathematical algorithms and computations.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> Power software such as <a rel="nofollow" class="external text" href="https://www.ipsa-power.com/">IPSA</a>, <a rel="nofollow" class="external text" href="https://www.skm.com/">SKM</a>, <a rel="nofollow" class="external text" href="https://www.cyme.com/">CYME</a>, DINIS, PSS/E, DIgSILENT and ETAP are pioneers in the category of power engineering software. Most of these products used <a href="MARKAL" title="MARKAL">MARKAL</a>, <a href="Energy_Technologies_Institute" title="Energy Technologies Institute">ESME</a> and other modelling methods. The transmission lines were designed according to minimum requirements set out in the SQSS (security and quality of supply standard). This also applies to other elements of the power systems. In the software world, many CAD software products for 2D and 3D electrical designs were developed.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup>

<div class="mw-heading mw-heading3"><h3 id="Renewable_Energy_Controller_Software">Renewable Energy Controller Software</h3></div>
<p>The controllers of <a href="Renewable_energy" title="Renewable energy">Renewable energy</a> used different software.

</p>
<div class="mw-heading mw-heading3"><h3 id="Power_Engineering_Protection_Software">Power Engineering Protection Software</h3></div>
<p>Another kind of software is one for simulating security systems for power systems and power plants. Such software simulates the activation of the various types of protections, which protects the transformers, power lines and other components. It graphs the different characteristics of the protections. Mathematical models have been set for all components of the power engineering system. It is up to the user to choose what type of protection to put on the energy objects. Protections are also mathematically modeled when they are connected to power engineering objects. The parameters of the emergency are set and based on the mathematical model, all the calculations are performed to obtain the output graphs and results.<sup id="cite_ref-9" class="reference"><a href="#cite_note-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup>
