This chapter will study the dynamics of irradiance and the power delivered to the grid by PV plants in time frames of less than 10 min, paying particular attention to the influence of PV plant size and geographic dispersion on magnitude and duration. We are now going to present some general models which make it possible to simulate the power fluctuations of either a power plant or a group of power plants, based solely on irradiance measurements. Finally, we shall study the control strategies required to compensate these fluctuations, based on storage systems installed in the PV plants, analysing the energy and power requirements to compensate these variations. |
