The review was informed by the following principles and considerations: • Facilitate the integration of these plants into the NEM – the technical requirements should support the operation of the power system for secure and reliable operation and not hinder greater participation of these plant in the market. [...] Since DER are expected to play a significant role in the power system of the future – and increasingly, in the power system of the present day – the ability of sub-5 MW DER to support the operation of the power system is also important, especially under emergency conditions where market arrangements alone may not be sufficient and system operations require additional measures to target resilience. [...] © AEMO 2024 | Technical Requirements for 200 kW – 5 MW Distributed Energy Resources 23 Prospective performance requirements • Where the plant is part of a hybrid system, being any combination of load and generation and storage, where the plant is controlling the net import or export at the connection point, and the ramp rate limit is applied to the net import or export, but the plant may be permit. [...] Some control modes may also cause the plant to respond to voltage disturbances in a way that opposes the disturbance (such as volt-var control), in which case the response of the plant also influences the 32 However, some requirements of AS4777.2 2020 exceed the requirements of the NER S5.2. [...] • Where the DNSP and the DER operator can agree another location for the reference point of applicability between the connection point and the DER terminals, instead of at the DER terminals.
