The development towards Smart Grids aims to \u00ab\u00a0optimally\u00a0\u00bb fulfil the aforementioned, and sometimes contradictory, requirements.<\/span><\/p>\n<p><span lang=\"en-GB\">The Networks Team contributes to these objectives with its scientific developments concerning <\/span><strong><span lang=\"en-GB\">the energy supervision and architecture of electrical networks <\/span><\/strong><span lang=\"en-GB\">of any type (<\/span><strong><span lang=\"en-GB\">land-based, offshore, on-board, housing, railways, etc.)<\/span><\/strong><span lang=\"en-GB\"> The major developments can be broken down as follows:<\/span><\/p>\n<ul>\n<li><span lang=\"en-GB\">Integration of <\/span><strong><span lang=\"en-GB\">decentralised sources and loads in the networks<\/span><\/strong><span lang=\"en-GB\">.

In addition, it incorporates a real-time simulator at the heart of its system. This can therefore be interfaced with real equipment using power amplifiers so as to take into account their behaviour in a real-life interaction with a network.<\/span><\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/l2ep.univ-lille.fr\/wp-content\/uploads\/plateforme-\u00e9nergies-r\u00e9parties.png\"><img loading=\"lazy\" class=\"aligncenter wp-image-1104\" alt=\"plateforme ER\" src=\"https:\/\/l2ep.univ-lille.fr\/wp-content\/uploads\/plateforme-\u00e9nergies-r\u00e9parties.png\" width=\"530\" height=\"406\" srcset=\"https:\/\/l2ep.univ-lille.fr\/wp-content\/uploads\/plateforme-\u00e9nergies-r\u00e9parties.png 662w, https:\/\/l2ep.univ-lille.fr\/wp-content\/uploads\/plateforme-\u00e9nergies-r\u00e9parties-300x229.png 300w\" sizes=\"(max-width: 530px) 100vw, 530px\" \/><\/a><\/p>\n<p><span style=\"font-size: medium;\"><span lang=\"en-GB\"><strong><span style=\"font-size: medium; color: #f07e1c;\">Examples of achievements<\/span><\/strong><\/span><\/span><\/p>\n<p><strong><span lang=\"en-GB\">Development of supervision techniques for electrical systems<\/span><\/strong><span lang=\"en-GB\"> whose status or behaviour is poorly known (random), whose time horizons to be integrated can be very short (real time to react to dynamic stresses) and long (e.g. one year in order to take into account the seasonality of renewable sources).
