技术领域Technical Field

During the use of the integrated photovoltaic, storage, charging and inspection microgrid station, safety issues are very important. However, most of the safety monitoring systems used in existing integrated photovoltaic, storage, charging and inspection microgrid stations are based on multiple functions for monitoring and safety performance evaluation, without considering the overall safe operation status of the system. This will result in the decentralized monitoring and evaluation system being unable to effectively identify safety hazards involving multiple devices and functional modules when there are no obvious outstanding safety hazards in the system. Therefore, how to provide a method for evaluating the operation safety of an integrated photovoltaic, storage, charging and inspection microgrid station is a problem that technicians in this field urgently need to solve.

进一步的，安全评价指标包括建筑安全指标、设备安全指标、光伏安全指标、储能安全指标、充电安全指标和消防安全指标。Furthermore, the safety evaluation indicators include building safety indicators, equipment safety indicators, photovoltaic safety indicators, energy storage safety indicators, charging safety indicators and fire safety indicators.
进一步的，S2具体为：Furthermore, S2 is specifically:
S21、确定每个运行参数指标分别对多个安全领域造成的不同后果；S21. Determine the different consequences of each operating parameter indicator on multiple safety areas;
