Abstract

The performance simulation of an open architecture energy management system (EMS) can provide detailed quantitative performance information long before a system is built. A method for simulating the performance of LAN-based EMSs is presented. The simulation shows how the performance of the system with respect to throughput and response time can be predicted. The results of the simulation of a generic LAN-based EMS for a typical operating scenario in a control center are presented. The simulation models the system hardware, including processor workstations, dispatcher consoles, memories, disks, LANs, file servers, etc. The LAN protocol and LAN data traffic are simulated. Typical EMS software functions are simulated. Dispatcher actions are simulated by random time event generators, which also simulate random power system events. Sensitivity analysis is performed by varying a number of system parameters to determine their effect on the simulated system. Outputs of the simulation show: utilization of the processors, consoles, LANs, and servers; LAN statistics; response times of display callups and supervisory control; and elapsed times of key EMS functions.<>

分布式能源管理系统的性能仿真

开放式体系结构能源管理系统(EMS)的性能仿真可以在系统构建之前提供详细的定量性能信息。提出了一种基于局域网的电磁系统性能仿真方法。仿真显示了如何预测系统在吞吐量和响应时间方面的性能。给出了一种基于通用局域网的EMS在控制中心典型操作场景下的仿真结果。仿真对系统硬件进行建模，包括处理器工作站、调度控制台、存储器、磁盘、局域网、文件服务器等。对局域网协议和局域网数据流量进行了仿真。对典型的EMS软件功能进行了仿真。调度程序的动作由随机时间事件生成器模拟，随机时间事件生成器也模拟随机电力系统事件。灵敏度分析是通过改变一些系统参数来确定它们对模拟系统的影响。仿真输出显示:处理器、控制台、局域网和服务器的利用率;局域网数据;显示调音和监控的响应时间;以及EMS关键功能的运行时间。
