“…The aggregate dynamic model has been developed, using MATLAB and Simulink, to study primary system-frequency dynamics during the initial post-contingency timeframe. Our analysis is limited to the first 30 s after the unbalance, where the highest stress for frequency stability is usually detected [29]. Therefore, only the PFC is considered, as the primary response shall be fully activated in <30 s [19].…”

“…The compensation factor is deduced from [17], which occurs from the fact that the frequency variations are high enough, and thus the swing equation mechanical and electrical powers do not void each other. The model for this compensation power is, from [17], introduces a gain factor K incorporating the frequency changes and the dead-band. The modified form for the control is shown in Figure 1 with the gain factor loop.…”

Frequency regulation is one of the basic objectives in ancillary market, which involves different stages and multiple participants. There exists different techniques for this service, where the points of demarcation are the time of service, and the regulatory requirements. The paper discusses primary frequency regulation, w.r.t Italian regulations, which is provided by conventional power plants upon TSO requests. The paper demonstrates conventional technique with its limitations, and proposes use of Virtual Power Plant (VPP) for the service provision. Storage and renewables techniques are compared under VPP context, and the use of storage is motivated. Finally, technical and economic comparison amongst potential storage techniques is done.

“…For example, the inertial response of the grid on power imbalances is determined by all rotating masses of the turbo-generators in the system. However, renewable power sources such as wind turbines and photovoltaics do not possess directly coupled rotating inertia, which reduces the robustness and stability of the power system [3][4][5].…”

As the share of renewable energy sources increases, the grid frequency becomes more unstable. Therefore, grid balancing services will become more important in the future. Dedicated devices can be installed close to the point where offshore wind farms are connected to the transmission grid on land. There, it can be used to attenuate power variations, reduce congestion and offer grid balancing. These ancillary services can create significant economic revenue. In this paper, the provision of the primary reserve by means of a large hydrogen electrolyser of 25 MW is investigated for the specific case of the Belgian transmission system. The electrolyser is used to convert water and excess power to hydrogen gas, which is injected into the natural gas grid. The revenue for primary reserve (R1) provision is analysed on a techno-economic model, including capital costs, operational costs, the revenue of the generated hydrogen and oxygen products and the ancillary service income. The revenue depends strongly on the contracted power-band. Therefore, it is optimised to yield maximum revenue. The results show that providing R1 creates a considerable revenue. Therefore, a large electrolyser can be a good candidate to buffer excess renewable energy into green gas while simultaneously providing grid support.
