摘要:: 随着微电网技术的快速发展,微电网的控制研究成为当前的研究热点。针对当前园区微电网控制系统在数据交互过程中存在数据来源可靠性和数据完整性保护等问题,提出一种消息可恢复式数字签名方案。该方案与一般的数字签名方案相比具有能够减少通信量、降低通信代价的优点,适用于带宽有限,计算能力弱的应用场景中,可以有效地应用到园区微电网的控制系统中,并保持微电网运行的高效性。园区微电网的控制是保障园区稳定供电的重要组成部分,针对园区微电网控制系统的网络安全问题,以消息可恢复式的数字签名方案为基础,进一步提出一种适用于园区微电网的安全控制协议。最后通过 C#轻量级密码术包对安全控制协议的交互过程进行实验与仿真,实验结果表明该方案的签名过程耗时短,表明该安全控制协议在控制器端运行效率较高,可以有效提高园区微电网控制系统的安全性,可以为园区微电网的安全稳定运行提供有力保障。

Abstract:: With the rapid development of microgrid technology,the research of microgrid control has become a hot topic. Aiming? ? ? at the problems of data source reliability and data integrity protection in the process of data interaction in the current? ?park microgrid controlsystem,a digital signature scheme with message recovery is proposed. Compared with the? ?general digital signature scheme,this scheme has the advantages of reducing communication traffic and communication cost,which is suitable for the application scenarios with limited bandwidth and weak computing power. Therefore,it can? be applied to the efficient microgrid in the park and maintain the high efficiency of the operation of the microgrid. The microgrid control is an important part to ensure the stable power supply in the park. Aiming at the network security problem of the control system of the micromigrid and based on the signature scheme with message recovery,a security control protocol is proposed for the microgrid control system in the park. Finally,the security control protocol is simulated by C sharp light weight cryptography package. Experimental results show that the security control protocol has the advantages of shorter time in scheme signature process and higher operation efficiency in the controller,which can improve the security of the microgrid control system in the park effectively,and can provide a strong guarantee for the security and stable operation of the microgrid in the park.
