Specifically, we derive a new necessary and sufficient condition for the small-signal stability of power systems in an analytically tractable form. Furthermore, based on this insight, we establish a systematic methodology for reducing a subset within the power system to an equivalent generator model while preserving its small-signal stability properties. This proposal can help reduce the computational burden, eliminate conservatism, and improve the analytical accuracy of large-scale stability analysis, thereby supporting more reliable decision-making in the planning and operation of future power systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePDFファイルサイズ：\u003c\/strong\u003e757Kバイト\u003c\/p\u003e","brand":"IEEJ-PDF","offers":[{"title":"PDFダウンロード（一般価格440円\/会員価格220円） \/ A4 \/ 10","offer_id":47681921646831,"sku":"IEEJ-BTB2025037-PDF","price":440.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/9512\/2159\/files\/IEEJ-PDF_bumontaikai_aadd2a9d-bdc8-41c8-b59e-a7edf89225c6.png?v=1770872546","url":"https:\/\/ieej.bookpark.ne.jp\/products\/ieej-btb2025037","provider":"電気学会 電子図書館","version":"1.0","type":"link"}
