电力市场覆盖范围广,市场成员分散,交易中心与市场成员之间需要交换大量市场私有信息。市场中用户类型众多,访问权限各不相同,并且受市场规则变动的影响。电力市场的信息保密性、用户多样性和访问权限多变性,要求支持市场运行的电力市场运营系统必须具备严格而且灵活的安全访问控制机制。为此,文中描述了硬件层、系统软件层和应用软件层相协调的安全访问控制的整体结构,设计了基于Java 2平台企业版(J2EE)架构的内嵌访问控制、动态代理和控制中心 3种应用层用户访问控制方案。对各方案的对比分析表明,控制中心方式安全性高,配置灵活,能够将权限管理与应用开发彻底分离,使应用开发人员专注于业务逻辑实现,以快速响应市场交易模式和访问逻辑的变化。基于该控制方式的区域电力市场运营系统已经投入现场运行。
There is a wide range of power markets, diversified market members and a large amount of private market information exchanged between trading centers and market members. There are many types of users in the market, access rights vary, and are subject to changes in market rules. Power market information confidentiality, diversification of user diversity and access rights, requiring support for market operation of the electricity market operating system must have strict and flexible security access control mechanism. To this end, the paper describes the overall structure of security access control coordinated by hardware layer, system software layer and application software layer, and designs embedded access control based on Java 2 Platform Enterprise Edition (J2EE) architecture. Dynamic Proxy and Control Center Application Layer User Access Control Scheme. The comparative analysis of various programs shows that the control center has the advantages of high security, flexible configuration and complete separation of rights management and application development, enabling application developers to focus on the implementation of business logic so as to respond quickly to changes in market trading patterns and access logic. The regional power market operation system based on this control mode has been put into operation on site.
