An attack-oriented, risk-aware feature modeling method constructs multi-dimensional temporal inputs by combining protocol semantics, operational interaction behaviors, and deviation-based risk indicators, which are processed by a BiLSTM backbone with time-step attention and channel-level attention fusion. Model pruning and attention sparsification are adopted to obtain a compact architecture suitable for edge deployment, while a dual-threshold, detection-driven defense coordination mechanism links anomaly scores to graded response policies and closed-loop control. Experiments on a hybrid dataset composed of real PV communication logs and PV-adapted UNSW-NB15 and CIC-IDS2018 traffic show that the proposed model achieves 94.8% accuracy, 94.2% recall, and a 95.6% F1-score with an average inference time of 16.2 ms and a false positive rate below 3.6%. Compared with a vanilla BiLSTM-Attention baseline, the proposed framework improves F1-score by 3.2 percentage points and reduces inference latency by about 11%, while maintaining higher robustness under noisy and imbalanced conditions. These results indicate that the framework can provide accurate, real-time intrusion detection and coordinated security defense for distributed photovoltaic communication networks in resource-constrained deployment scenarios.Povzetek:An improved lightweight multi-channel BiLSTM-Attention framework enhances intrusion detection and coordinated security defense in distributed photovoltaic communication networks through risk-aware temporal modeling, multi-channel attention fusion, and model pruning for edge deployment.<\/jats:p>","DOI":"10.31449\/inf.v50i11.13224","type":"journal-article","created":{"date-parts":[[2026,4,23]],"date-time":"2026-04-23T19:36:11Z","timestamp":1776972971000},"source":"Crossref","is-referenced-by-count":0,"title":["Lightweight Multi-Channel BiLSTM-Attention with Coordinated Defense for Intrusion Detection in Distributed Photovoltaic Communication Networks"],"prefix":"10.31449","volume":"50","author":[{"given":"Danni","family":"Liu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shengda","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chunhui","family":"Shi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jia","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiuhong","family":"Jiang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"16141","published-online":{"date-parts":[[2026,4,23]]},"container-title":["Informatica"],"original-title":[],"link":[{"URL":"https:\/\/www.informatica.si\/index.php\/informatica\/article\/download\/13224\/6661","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.informatica.si\/index.php\/informatica\/article\/download\/13224\/6661","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,23]],"date-time":"2026-04-23T19:36:12Z","timestamp":1776972972000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.informatica.si\/index.php\/informatica\/article\/view\/13224"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,4,23]]},"references-count":0,"journal-issue":{"issue":"11","published-online":{"date-parts":[[2026,4,23]]}},"URL":"https:\/\/doi.org\/10.31449\/inf.v50i11.13224","relation":{},"ISSN":["1854-3871","0350-5596"],"issn-type":[{"value":"1854-3871","type":"electronic"},{"value":"0350-5596","type":"print"}],"subject":[],"published":{"date-parts":[[2026,4,23]]}}}
