With the rapid development of smart grid technologies, communication networks have become core infrastructure supporting control and energy optimization in microgrids. However, excessive reliance microgrid on faces dual challenges: On one hand, high-frequency information exchange under traditional periodic patterns causes severe waste network resources; other cyberattacks may cause loss, abnormal delays, or data tampering, which can ultimately lead to system instability. To address these challenges, this paper investigates secure dynamic integral event-triggered stabilization photovoltaic microgrids multimodal deception attacks. resource constraints (PV) systems, a integral-event-triggered scheme (DIETS) is proposed. This employs average processing historical state filter out redundant triggering events caused by noise disturbances. Simultaneously, time-varying threshold function designed integrating real-time states trends, enabling adaptive adjustment thresholds. In terms cybersecurity, strategy against multi-modal attacks incorporated enhance resilience. Subsequently, through Lyapunov–Krasovskii functional Bessel–Legendre inequality, collaborative design conditions for controller gain matrix are formed as symmetric linear inequalities ensure stability. The simulation results demonstrate that DIETS recorded only 99 events, achieving 55.2% reduction compared normal (ETS) 52.6% decrease relative ETS, verifying outstanding effectiveness DIETS.
