“…In PV mode, the corresponding bus can be modelled as a PV bus and the reactive power control is applied on the wind unit terminal. However, the wind units are usually operated at unity power factor in steady‐state conditions and the corresponding bus is modelled as a PQ [38]. Since in this paper the focus is on the pattern of wind speed, it is assumed that wind units inject power at unity power factor in PQ modes.…”

“…The share of renewables in global electricity generation is expected to rise to 30% by 2022 mainly due to growth in wind and solar generation capacity [1]. Realisation of high wind and solar penetration in moderately interconnected power systems entails addressing several aspects including, intermittency, reactive power scarcity, network capacity limitations and fault behaviour, among others [2,3]. A dispatchable generation unit can change its output, within the announced operational limits, per the request of the system operator.…”

Dispatchable renewable generation is essential for 100% renewables power system. It is in the interest of both power system operators and customers since it reduces the need for flexibility and reserve. To this end, battery energy storage systems (BESS) are proposed for integration in the renewable power plant. This paper presents the optimal dispatch unit for a dispatchable hybrid solar-wind power plant with BESS framework. It achieves optimal dispatchable renewable generation (from dispatchable hybrid renewable (solar-wind) power plant with BESS, DHRB, operator perspective), subject to operational limits, by exploiting the synergy of wind and solar energy and combining it with storage capability of BESS using two different operation strategies, maximisation of revenues and maximisation of renewables harvesting. A continuous BESS degradation model is incorporated in the proposed rolling-algorithm-based-optimal dispatch unit to improve the accuracy of results. The applicability of the proposed methodology and the performance of the operation strategies are demonstrated using a case study and the operation strategies are compared. Further, the effect of BESS size on its degradation and dispatchable power in a hybrid solar-wind power plant with BESS are investigated through BESS lifetime. An indicative economic analysis is carried out to provide ground for the extra investment on and sizing of BESS for a dispatchable hybrid renewable power plant.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…Many previous works concern optimal planning of wind power capacity. For example, [4] uses a long‐term voltage stability constrained OPF to find the optimal capacity allocation of wind power in order to maximise the voltage stability margin. However, here the focus is on the short‐term problem given the market outcome.…”
