The rapid expansion of distributed energy resources and variable renewable energy is occurring in most utilities around the world, pertaining to the clean energy transition. These technologies have brought new challenges and opportunities to transmission grid planners. In this context, the planning process cannot continue to focus solely on the instant of the peak demand to make decisions regarding the evolution of the grid. The OSER simulator (Outil de simulation de l’exploitation du réseau) presented in this paper allows the planning engineers to consider operational and transversal aspects (transmission and distribution view) of the system. OSER is composed of several modules, each of which is related to different parts of the utility. The load, interconnection, and production modules prepare profiles for each substation, interconnection, and generating unit, respectively. The virtual operator module models the actions and mitigation means of the grid operators. These include the generation load balance, voltage, reactive power control, and interconnection management. Thereby, OSER can simulate the reaction of the transmission system for all relevant scenarios by using the guidance of the transmission system operator. The results obtained by simulation validate the performance of the OSER simulator by comparing them with historical data. This tool enables transmission grid planners to include non-wire alternatives in their planning process. Further work will be conducted to extend the simulation modes towards year-long and stochastic simulations for better planning robustness.

OSER——电力系统运行仿真和分布式能源对输电系统影响评估的规划工具


分布式能源和可变可再生能源的快速扩张正在世界各地的大多数公用事业中发生，这与清洁能源转型有关。这些技术给输电网规划者带来了新的挑战和机遇。在这种情况下，规划过程不能继续仅仅关注峰值需求的瞬间来做出有关电网演变的决策。本文提出的 OSER 模拟器（Outil desimulation de l'exploitation du réseau）允许规划工程师考虑系统的操作和横向方面（传输和分配视图）。 OSER 由多个模块组成，每个模块都与实用程序的不同部分相关。负载、互连和生产模块分别为每个变电站、互连和发电机组准备配置文件。虚拟运营商模块对电网运营商的行动和缓解手段进行建模。其中包括发电负载平衡、电压、无功功率控制和互连管理。因此，OSER 可以在传输系统操作员的指导下模拟传输系统对所有相关场景的反应。仿真获得的结果通过与历史数据的比较验证了OSER模拟器的性能。该工具使输电网规划者能够将非电线替代方案纳入其规划过程中。我们将开展进一步的工作，将模拟模式扩展到为期一年的随机模拟，以提高规划的稳健性。
