随着新能源快速发展,新型电力系统建设步伐逐渐加快,传统跟网型新能源装机规模不断攀升,由于缺乏传统同步发电机等主动支撑型电源,电网稳定性问题日益凸显。为了解决弱电网所带来的一系列问题,发展具备主动支撑能力的构网型新能源已成为重要解决手段。针对构网型光伏大扰动短路试验,不仅进行了详细试验方案评估,还对并网短路和孤网短路试验数据进行了对比,以及基于电力系统全数字实时仿真(ADPSS)分析了机电-电磁混合仿真计算值和试验值的误差。试验达到了预期目的和效果,验证了构网型光伏在故障期间具备构网特性和系统构建与稳定支撑能力
同时对构网型光伏与跟网型光伏系统进行了支撑能力量化比较,最后给出了构网型装备下一步工作期望。
With the rapid development of renewable energy
the pace of new power system construction is gradually accelerating
and the installed capacity of traditional grid-following renewable energy is constantly increasing. Due to the lack of active grid-supporting power sources such as traditional synchronous generators
the stability of the power grid is becoming increasingly prominent. In order to solve a series of problems caused by weak grids
developing grid-forming renewable energy with active grid-supporting capability has become an important solution. In response to the short-circuit test of the grid-forming photovoltaic under large disturbances
a detailed test plan evaluation is conducted
and the data of grid-connected short-circuit and islanded short-circuit tests are compared. Based on the advanced digital power system simulator (ADPSS)
the errors between electromechanical-electromagnetic hybrid simulated and field-measured values are analyzed. The test achieves the expected goals and effects
verifying that the grid-forming photovoltaic system has the grid-forming characteristics
system construction and stable support capability during faults. At the same time
a quantitative comparison of the support capability of the grid-forming photovoltaic system and the grid-following photovoltaic system is made. Finally
the next step of work expectations for the grid-forming equipment is given.
