与输电和配电系统相连的可再生能源产生的电能和同步发电机的排量继续增长。这预示着一种范式--从传统的提供辅助服务转变为从提供同步和非同步发电(包括与配电连接的资源)，从提供与输电相连的同步发电机，到提供对确保一个健全的系统至关重要的辅助服务。鉴于可供系统运营商使用的资源不断增加，运营网络的灵活性可以扩大。在此背景下，本文提出了一种专用于无功供电的电压辅助服务策略。拟议战略的一个主要特点是，它是技术中立的，不像现有的专注于同步发电机的战略。该策略将系统对电压稳定性的需求放在核心位置，将其转化为对无功提供的要求。该策略通过分布式发电和传统资源的综合利用，实现了推迟无功补偿设备的投资。为了验证该策略的技术优势，进行了动态和暂态研究，并通过半实物测试验证了该策略的实际可行性。
The electrical energy generated from renewable energy resources connected to transmission and distribution systems and the displacement of synchronous generators continues to grow. This presages a paradigm-shift away from the traditional provision of ancillary services, essential to ensure a robust system, from transmission-connected synchronous generators towards provision from synchronous and non-synchronous generation (including distribution-connected resources). Given that the available resources at the disposal of system operators are continuously increasing, the flexibility for operating the network can be enlarged. In this context, this paper introduces a dedicated voltage ancillary services strategy for provision of reactive power. A main feature of the proposed strategy is that it is technology-neutral, unlike existing ones that are focused on synchronous generators. The system need for voltage stability is placed at the core of this strategy, which is translated into a requirement for reactive power provision. The proposed strategy achieves, through the combined utilization of distributed generation and traditional resources, to defer the investments in reactive compensating equipment. Dynamic and transient studies are conducted to demonstrate the technical benefits of the strategy, while its practical feasibility is also validated through hardware-in-the-loop testing.
