Modeling of LF fluctuations induced to the power grid with renewable generation

Dynamics of modern grid are determined from the ever increasing penetration of renewable sources in the generation mix, even at the distribution level. Power electronics facilitate this penetration and allow the de-centralized control of the grid. Moreover they allow the transformation of the loads into “smart loads” so that they participate in grid dynamics, even at the LV grid operation. The interaction of smart loads with the grid through is performed by DR strategies, edge load management as well by mitigation of the fluctuations induced in the grid from the intermittent nature of the renewable generators. Since grid frequency fluctuations, stemming from renewable's output volatility, are connected to the electricity prices, the interaction of the grid with many smart loads allows the stochastic exploration of the grid dynamics of a decentralized grid.
