本文分析了构网型储能与分布式调相机的工作原理及优劣特性,调研了二者典型技术特性差异情况,将构网型储能的有功功率支撑强、全生命周期经济性优异但运行安全裕度有限与分布式调相机的无功功率过载能力强、安全性高但长期运维经济性欠佳特性结合,提出面向新能源场站的强惯量支撑、高安全可靠性、高经济性的多元复合主动支撑技术方案。并依托RTLAB半实物仿真平台,接入行业头部设备厂商真实物理控制器,搭建含构网型储能、分布式调相机、光伏场站的弱电网新能源场站仿真系统,完成弱电网下构网型储能与分布式调相机暂态特性对比分析,并开展多种主动支撑配置方案对新能源场站并网发电能力提升对比仿真。仿真结果表明,构网型储能可呈现与分布式调相机相近的暂态电压/频率支撑性能,所提构网型储能+分布式调相机的多元复合主动支撑方案可充分发挥两种惯量支撑设备的技术优势,弥补单一技术方案的不足,降低新能源场站投资成本,同步提高系统综合扰动抑制能力及场站全生命周期经济效益。
This paper analyzed the operating principles
performance merits and demerits of grid-forming energy storage and distributed synchronous condensers
and investigated the differences in their typical technical characteristics. By integrating the technical and economic features of grid-forming energy storage
which featured strong active power support
excellent full-life-cycle economic efficiency yet limited operational safety margin
with those of distributed synchronous condensers
which strong reactive power overload capacity
high operational safety but unsatisfactory economic performance in long-term operation and maintenance
and proposed a multi-integrated active support scheme with high inertia support capabcity
superior safety reliability and economic efficiency is proposed for renewable energy power plants. On the RTLAB hardware-in-the-loop simulation platform
actual physical controllers supplied by leading mainstream manufacturers are incorporated to establish a weak-grid simulation model of renewable energy power plants
which integrates grid-forming energy storage
distributed synchronous condensers and photovoltaic stations. Comparative analysis on the transient performance of the two devices under weak grid conditions was completed . Moreover
comparative simulations were performed to evaluate the improvement in grid-connected power generation capability of renewable energy power plants under different active support configuration strategies. Simulation results demonstrated that grid-forming energy storage delivered transient voltage and frequency support performance similar to distributed synchronous condensers. The proposed hybrid active support scheme combining grid-forming energy storage and distributed synchronous condensers can fully exploit the technical advantages of the two inertia support devices and compensate the deficiencies of individual schemes. Meanwhile
it can reduces the investment cost of renewable energy power plants
and simultaneously enhances the comprehensive disturbance suppression capability as well as the full-life-cycle economic benefits of the power stations
