In this paper we study dynamical distortion problems in future electrical energy systems with high renewable penetration. We introduce a new time-domain modeling of electrical energy systems comprising inverter-controlled distributed energy resources (DERs). This modeling is first used to quantify the relations between distortions and real/reactive power dynamics. Next, to ensure acceptable Quality of Service (QoS), a novel nonlinear distributed inverter control is introduced. Sufficient conditions are established for the guaranteed performance of the proposed control. These conditions further support the practical implementation of the derived controller. The effectiveness of this enhanced control is illustrated using simulations for the case of avoiding system instability during sudden grid reconfigurations. Simulations also show that distortions can be suppressed in systems with parallel-connected solar photovoltaics (PVs).

未来电能系统中的高质量服务：一种新的时域方法

在本文中，我们研究了具有高可再生性的未来电力系统中的动力畸变问题。我们介绍了包含逆变器控制的分布式能源（DER）的电能系统的新时域建模。该模型首先用于量化失真与有功/无功动态之间的关系。接下来，为了确保可接受的服务质量（QoS），引入了一种新颖的非线性分布式逆变器控制。为保证所提出的控制措施的性能建立了充分的条件。这些条件进一步支持派生控制器的实际实现。使用仿真来说明这种增强型控制的有效性，以避免在突然的电网重新配置期间出现系统不稳定的情况。
