In　this　paper,　taking　the　architecture　and　configuration　of　hybrid　control　systems　(HCS)　as　the　key　gist,　some　concepts,　characteristics　and　properties　of　HCS　are　discussed　in　depth.　Meanwhile　the　hybrid　characteristics　and　the　related　issues　of　electric　power　system　are　briefly　analyzed　so　that　the　advantages　and　originalities　of　HCS　methodology　in　tackling　some　difficult　problems　of　optimizing　schedule　and　stabilized　control　for　electric　power　systems　are　manifested.　Finally,　some　mathematical　foundations　and　technical　support　tools　from　other　disciplines　in　the　research　on　hybrid　control　systems　are　recommended,　thus　some　key　topics　in　the　research　on　HCS　are　outlined.
