技术领域technical field
本发明属于电力系统自动化技术领域，具体涉及一种用于电力市场交易服务调用的实现方法及装置。The invention belongs to the technical field of electric power system automation, and in particular relates to a method and a device for realizing transaction service calls in electric power markets.
背景技术Background technique
电力市场交易平台不同应用之间以及电力市场交易平台与调度平台应用之间都存在服务调用需求。目前电力交易平台内部不同应用之间，如交易与合同、计划与结算以及各应用与模型之间的访问需求都是基于程序编码和数据库紧耦合实现；电力交易平台与调度平台之间也存在联络线发输电能力计算、安全校核等服务调用需求，目前是通过系统外人工确认实现。由于电力市场交易平台内部以及与调度平台间缺少一种服务调用机制，导致电力交易平台内部应用之间以及与调度平台间通信效率和信息交互复用性低，而程序耦合度和出错机率高。There are service call requirements between different applications of the power market trading platform and between the power market trading platform and dispatching platform applications. At present, the access requirements between different applications in the power trading platform, such as transactions and contracts, planning and settlement, and between applications and models, are all based on program codes and tight coupling of databases; there is also a connection between the power trading platform and the dispatching platform. Service call requirements such as line generation and transmission capacity calculation and safety verification are currently realized through manual confirmation outside the system. Due to the lack of a service call mechanism within the power market trading platform and between the dispatching platform, the communication efficiency and information interaction reusability between the internal applications of the power trading platform and between the dispatching platform are low, while the program coupling degree and error rate are high.
