Eventually, PV power can become flexible enough to be dispatchable. Moreover, the support services needed by PV power can be undertaken mainly by itself, thus enabling high penetration. From the literature, PV forecasting, energy storage, and inverter-controlled curtailment are identified to be cornerstones of dispatchable PV power.
It is found that increasing the dispatchability of solar power plants will necessarily lead to the emergence of additional energy losses and important LCOE increase, either because of low round-trip efficiency of the storage system, or because of its high cost of energy capacity.
Concentrating solar power systems with TES are dispatchable, increasing overall grid flexibility and allowing for greater penetration of other non-dispatchable renewable resources such as PV and wind (Denholm and Mehos 2011 ). Similarly, Cocco et al. ( 2016) improve power dispatchability, but instead use concentrated photovoltaics.
Despite the challenges, PV penetration is growing and needs to grow further. Overcoming the challenges means eliminating intermittency using minimum storage and negligible fuel. The solution is effectively converting PV to a dispatchable source.
Although dispatchable generation is unlikely achieved solely by PV power in the near future, the literature has motivated building abundant PV capacity for dispatchability. 6. Research opportunities 6.1. Energy management algorithms for Cat 4 PV So far, high-level control planning algorithms implementing Cat 4 PV power has rarely been demonstrated.
Shifting from intermittent to dispatchable solar electricity production induces additional constraints on the plant operation, which should satisfy a predefined electrical load rather than intermittently injecting solar electricity in the grid.
