“…Some studies have addressed flexibility services provision in NI from batteries within the Social Housing sector to provide ancillary services [17], since NI has large scattered rural areas resulting in a long transmission and distribution networks. Since hospitals also have large loads connected to the DN, and 90.5% of the wind power which is responsible for more than one third of total NI demand is also connected to the same stringy and long DN, there is great potential for hospitals to be a new player as a flexibility provider for the power system, to reduce the curtailment of clean energy from RES and to be part of achieving net zero emissions reduction targets.…”

The ambitious target of reaching net-zero greenhouse gas emissions by 2050 in the UK, which includes the decarbonisation of heat and electricity, means the increase of instantaneous power from non-dispatchable renewable energy sources (RESs). The intermittency of RESs will cause stability issues for the grid resulting from the mismatch between generation from RES and load demand. Battery energy storage systems (BESS) can match loads with generation and can provide flexibility to the grid. This study is proposing the health sector as a new flexibility services provider for the grid through BESS. The health sector has large loads that run throughout the year, and by managing this load it can provide flexibility to the grid. Four different scenarios have been evaluated for a range of behind-the-meter (BTM) BESS for a hospital in the UK to provide arbitrage and ancillary services considering the option of installing a photovoltaic (PV) system. It was found that BESS would not be economically viable through arbitrage alone since the payback period was always greater than the BESS lifetime. However, bundling services by participating in the ancillary services market resulted in payback periods as low as 3.10 years for some systems, and the net present value (NPV) could reach more than £5 million. This work provides evidence that the health sector can be a significant player in the transition to a renewables-led energy system, an exemplar for other sectors, and one of the solutions to recovery from the COVID19 pandemic.

“…The island of Ireland had thirty-four low frequency events in the period between October 2018 and September 2019, and the frequency nadir reached as low as 49.4 Hz [17]. Furthermore, in NI, the power system inertia needed to allow an SNSP of 75% can be achieved through synthetic inertia provided by a 360 MW BESS [44].…”

“…In [42], through an 11 kV substation of a campus distribution network, a 2 MW/4 MWh storage was deployed to increase self-consumption of wind energy; new wind turbines and batteries were simulated for flexibility gains within the distribution network in [49]. Demand response strategies have been described to manage network congestions while providing ancillary services through the network using different levels of load portfolios in [50], moving loads from peak to off-peak periods in [51]; and residential batteries are described for peak shaving in [52].…”

“…The first three of those papers analyse flexibilities offered by specific technologies, while the remaining target at value from multi-resourced flexibilities. References [12,13] place emphasis on the application after recognising the value of flexibilities; both mention the implication of flexibilities in dealing with network issues.…”

With the launch of global decarbonisation, the infiltration of low-carbon distributed energy resources (DERs) is increasing. The future transaction platforms for those flexibilities are considered to be peer-to-peer (P2P) ones conforming to resources' characteristics of small-scale and independence. This research reviews current flexibility-related topics and proposes one P2P flexibility market filling in the gaps. The contribution of this research includes: (1) it constructs a flexibility market combining pricing strategy and matching strategy of the mature and successful real-world P2P business models, accommodating the penetration of DERs. The proposed automatic trading market could mobilise the enthusiasm of market participants and satisfy individuals' needs for a convenient market. (2) it proposes a dynamic pricing strategy where prices fluctuate with the features and portfolios of market participants. More adequate market signals are provided with the promotion of market equity. (3) it discusses the segmentation tendency of the flexibility market when considering energy products as pure commodities following the disintegration from the transmission system operator to the distribution system operator. The feasibility of the proposed market under future energy scenarios is thus explored.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.
