The ability to avoid curtailment is a function of both the power and energy capacities of the energy storage device. We perform simulations with varying energy storage sizes to examine curtailment reduction with a focus on the role of duration.
Installation of the energy storage unit (ESU) in complement with a large wind farm/solar station is an effective way to reduce renewable power curtailment [ 5 - 7 ], since the investment on transmission corridor is usually more expensive and time-consuming while decreasing the utilisation rate of the transmission system.
A PV power curtailment algorithm is developed to limit PV power when power fluctuation exceeds the power capacity of the HESS. A multi-objective optimization model is established to dispatch the HESS power, considering energy losses and the state of charge (SOC) of the supercapacitor.
With PV curtailment, PV generation is curtailed in the central hours of the day. Table 6. Optimal decisions of ESS sizes and sites for case A (with PV curtailment). Fig. 7 shows the cumulative distribution function (CDF) of all voltages and currents for all the timesteps, scenarios and nodes/lines.
In these works, the PV plants are modeled as uncontrollable power injections without the possibility of curtailing any power; not exploring the potential trade-offs between ESSs and PV curtailment might result in large, and possibly sub-optimal, energy storage capacity requirements.
A shift in thinking toward curtailment management rather than prevention could increase the value of delivered and curtailed PV output to the grid. Various grid flexibility measures—including flexible generation, storage, load flexibility, and regional coordination—could be key components of a curtailment management scheme.
