The increasing penetration of non-controllable renewable energies connected to the grid via power electronics is rapidly changing the characteristics of electricity networks. In particular, the loss of inertia is a major challenge for the stability of these networks. Throughout the world, changes in the organisation of frequency reserves are gradually being observed on some islanded networks with a high penetration of renewable energy. Primary reserve requirements are changing and faster services are emerging, often called Fast Frequency Response or Synthetic Inertia.
Objectives / Missions
Within the European H2020 project XFLEX HYDRO, some hydroelectric producers and equipment manufacturers are trying to anticipate these trends. The objective of the role will be to study the evolution of the need for fast frequency control in continental Europe.
The main mission consists in developing simplified dynamic models to assess the frequency stability (RoCoF, nadir, steady-state frequency deviation) of the European grid considering the evolution of the energy mix and the associated interface with the power network (e.g., conventional synchronous generation or power electronics devices) [1,2]. Indeed, depending on the technology used, the activation rate of the primary frequency reserve can vary, which has a direct impact on the system frequency stability. The developed simplified model will therefore be used to determine the required reserve amount and activation speed considering different energy mix scenarios.
- To develop a simplified dynamic model of the European Grid for frequency stability analysis
- To extend the simplified model into a multi-nodal model of the grid allowing to represent the exchange capacity between regions.
- To characterize the dynamic response of different technologies for frequency support (hydro generators, coal power plants, power-electronics-interfaced energy sources, etc.)
- To study the evolution of synchronous inertia as function of the energetic mix in the grid
- To study the current methodology to size the frequency containment reserves in Europe and how this reserve is shared between different TSOs and its implications on the dynamic behavior of the grid.
- To propose a methodology to quantify the need of faster frequency reserves as function of the evolution of the energetic mix and inertia
- To propose a methodology for the placement of the future reserves taking into account the exchange capacity and the dynamic behaviour of the grid.
