What is WP5 about?

Work package 5 takes the concept developed in WP 3 and trials these concepts on live Irish electrical networks. WP5 is about trialling new devices and technics to accommodate more load and renewable generation with low system inertia on the system.

What are the goals of the WP5?

There are two key demonstrations, the first of which are the Irish trials. Installed in ESB’s networks, this trial consists of V2G charging devices, solar panels with smart inverters, battery storage behind the meters and air source heat pumps (ASHP). These devices will take part in trials to demonstrate ancillary services provision that can be achieved by controlling them in a coordinated fashion. These devices will be used to stabilize voltage in a region and will be controlled from a central platform called SERVO. RWTH is developing a smart inverter that will provide voltage support to the local electrical systems. This will be trialled also in WP5.

The second demonstration is trialling a pan-European real-time simulation infrastructure used to demonstrate frequency control and interconnection of laboratories in UCD and RWTH.

Which research concepts will be validated in these demonstrators?

Two research concepts will be validated in the trials.

• The first is the application of Middlebrook Theory on AC three phase systems and will be validated for voltage stabilisation.
• The second is called Linear Swing Dynamics and will be validated to define the state-of-the-art models of frequency dynamics and other frequency controllers of non-synchronist devices.

How is the work done in WP5 related with the others?

WP5 builds upon output deliverables from WP 2, 3, and 4 and validates the concepts in real world trials. The deliverables from WP5 are then fed into WP6.

Which are the expected results and how they will impact the success of RESERVE?

The research concepts developed will potentially stabilize system voltage and frequency on electrical systems that have low system inertia. This will allow additional renewables to connect to the electrical network and also accommodate new heavy loads such as EVs and heat pumps, while also minimizing network investments.
