Free QuoteConclusion This paper proposes a fuzzy-based control strategy for the grid-connected solar photovoltaic system to participate in primary frequency regulation without any energy storage support. A combined fuzzy based de-load control and control mode selector was proposed to enable PV operation at a scheduled level of power reserve.
This has resulted in the reduction of rotational inertia of the power system and thereby affecting the system frequency regulation capability. In view of this, there is an increasing need for PV also participating in frequency regulation of the system.
With the rapid expansion of new energy, there is an urgent need to enhance the frequency stability of the power system. The energy storage (ES) stations make it possible effectively. However, the frequency regulation (FR) demand distribution ignores the influence caused by various resources with different characteristics in traditional strategies.
To extend the service of PV to secondary frequency regulation it needs to be de-loaded for a longer period of time this may reduce the utilization factor of the plant. In summary, the inertial response from PV provides sufficient time for the governor control to take over the action.
Grid-tied PV operating in MPP do not have any stored energy to participate in frequency regulation. Hence to enable PV to participate in frequency regulation it is to be de-loaded so that a portion of power output is available for frequency regulation.
This power reserve is utilized to assist PV to participate in frequency regulation to improve under frequency response during low system inertia period. Fig. 7. Power control strategy of DC/DC converter. The P max estimator shown in Fig. 7 computes the MPP of the PV array even when the system is not operating in MPP mode.
