摘? 要: 隨著國家深化電力體制改革工作的不斷推進,中長期電力交易品種和交易頻次近年來也呈現快速增多的態勢,新一代電力交易系統已引入云計算、微服務、大數據等最新IT技術,為了更好地提高多級電力交易系統之間的快速協同,本文提出了一個基于服務網格技術框架的三級協同電力交易系統應用設計方案,該方案優化了電力交易系統從單體架構演進到分布式架構后的復雜服務調用時的執行效率。通過多個場景的測試,驗證了該方案可以降低三級電力交易系統結構復雜度、優化服務器使用開銷、提升三級系統應用的性能和執行響應速度,是分布式電力交易系統優化提升的一種不錯選擇。

【Abstract】: AbstractWith the continuous advancement of the countrys deepening of the power system reform, the medium and long-term power trading varieties and trading frequency have also shown a rapid increase in recent years. The new generation of power trading systems has introduced the latest IT technologies such as cloud computing, microservices and big data. In order to better improve the rapid coordination between multi-level power trading systems, this article proposes an application design scheme of three-level collaborative power trading system based on service mesh technology framework. This scheme optimizes the execution efficiency of the complex service invocation after the power trading system evolves from a single architecture to a distributed architecture. Tested in multiple scenarios, it is verified that the scheme can reduce the structural complexity of the three-level power trading system, optimize server usage overhead and improve performance and execution response speed of three-level system applications. It is a good choice for optimization and improvement of distributed power trading system.

當前,按地域劃分,國家電網管理區域的電力交易可分為跨區、區域內省間和省內電力交易。隨著《中共中央、國務院關于進一步深化電力體制改革的若干意見》(中發[2015]9號)及其配套文件發布[1],電力市場化交易的規模每年都在快速增長,同時,為了滿足各地經濟發展的需要和新能源消納的需要,中長期電力交易品種和交易頻次近年來也呈現快速增多的態勢,這就對當前三級電力交易組織提出了新的挑戰。……
