dc.description.abstractThere are currently about 100 GW of PV power installed in the Continental European power system that influences both the demand and supply sides of the electrical grid, except for the cases where they are equipped with energy storage systems, which is an unpopular configuration today for small behind-the-meter installations. In most of the cases, the solar energy is self-consumed in home appliances, which can be considered a sudden variation of the power demand for the system operators. On the other hand, surplus energy that is not self-consumed is sent back to the grid, causing potential sudden alterations of the power supply in the network. Additionally, the number of electric vehicles (EVs) connected to the grid is growing, mostly affecting the demand side's power patterns. In this sense, the 3 GW of primary reserve procured across Europe corresponds to charging approximately 10 thousand EVs with fast chargers at 300 kW or charging 300 thousand EVs with domestic chargers at 10 kW. Furthermore, it is worth noticing that today, over 1 million plug-in EVs are registered in Europe, and the numbers are rising. The same trend can be observed in pools of cloud aggregated assets, such as decentralized loads, generation, and energy storage systems, that exchange power with the grid in one or both directions. Considering that over 30% of all PV inverters and most charging stations are now connected to a cloud service through the internet, the amount of power for primary reserve is not sufficient to cover a simultaneous disconnection/reconnection of these devices. Even though these devices can be intentionally controlled for balancing purposes, the control of the pool through the cloud can also fail or be hacked and misused by hackers due to cybersecurity breaches. These non-intentional and undesired control actions raise the questions about grid frequency stability and the amount of power to be procured and kept available for control reserves in future. This paper provides insights about the impact on power systems caused by the malfunction or sudden loss of a large pool of Original Equipment Manufacturer assets in terms of system frequency dynamics and highlights the need for frequency reserves. Under this context, simulation results with the initial dynamic model of Continental Europe, developed by ENTSO-E, are analyzed, and discussed for different test cases considering current and future scenarios.de_CH
