摘　　要：电力体制改革的不断推进促使电力交易用户规模快速增长,电力市场技术支持系统在信息外网承受了更大的市场成员交易集中申报压力。在分析目前系统并发性能瓶颈现状基础上,提出了适应海量市场成员高并发访问的总体技术方案,并对微服务技术、数据访问优化、负载均衡、容器技术和公有云等关键技术进行了研究。在国家电网公司电力市场技术实验室搭建内外网逻辑强隔离真实环境进行了并发交易申报的压力测试,验证了所提技术方案可极大提升系统并发访问能力,并具备良好的可扩展性。The continuous promotion of power system reform has promoted the rapid growth of the scale of electricity trading participants,and the electricity market technical support system faces more pressure of centralized declaration of the market members in the information extra-net.Based on the analysis of the system concurrency performance bottleneck,an overall technical scheme to adapt to the high concurrency access of the massive market members is put forward in this paper.Meanwhile,the key technologies such as micro-service technology,data access optimization,load balancing,container technology and public cloud are studied and analyzed.Finally,a real environment with logic isolation between the internal and external network is built in the electricity market technology laboratory of the State Grid Corporation of China to conduct the stress test of concurrent trading bidding,which verifies that the proposed technical scheme can greatly improve the concurrent access ability of the system and has good scalability as well.
