“…With growing concerns regarding the security, reliability, and affordability of energy, the idea of sharing electricity generated by DRES is gaining popularity with scientists, policymakers, and communities alike [50]. Sharing of battery storage energy as compared to split distribution has proven to be a cost effective and viable solution in community scale systems such as high self-consumption, self-sufficiency, and cost savings to prosumers [51][52][53]. There are multiple reasons for this: first, large storage systems could easily participate in power markets.…”

“…Any unused electricity generation due to lower than expected demand will be exported to the grid ensuring the battery storage is full. It is necessary here to use the PV to charge the battery, otherwise the expected increase in self-sufficiency from grid charging and BESS discharging will be lost [51]. For the purpose of monitoring the data from SEM, submetering based on pulse meters were added to configurations as shown in Figure 2.…”

Shared Solar and Battery Storage Configuration Effectiveness for Reducing the Grid Reliance of Apartment Complexes

2020

More than 2 million houses in Australia have installed solar photovoltaic (PV) systems; however, apartment buildings have adopted a low percentage of solar PV and battery storage installations. Given that grid usage reduction through PV and battery storage is a primary objective in most residential buildings, apartments have not yet fully benefited from installations of such systems. This research presents shared microgrid configurations for three apartment buildings with PV and battery storage and evaluates the reduction in grid electricity usage by analyzing self-sufficiency. The results reveal that the three studied sites at White Gum Valley achieved an overall self-sufficiency of more than 60%. Owing to the infancy of the shared solar and battery storage market for apartment complexes and lack of available data, this study fills the research gap by presenting preliminary quantitative findings from implementation in apartment buildings.

“…The proposed modified I-V droop method controls power contributions from individual households such that each household contributes according to the capacity and the state of charge of its battery. To effectively coordinate distributed storage resources, many recent studies have adopted the concept of peer-to-peer (P2P) trading to develop optimization models to determine optimal schedules of ESSs and trading decisions, such as [36]- [38]. The authors in [38] investigated the optimal ESS operation and sizing problem in a P2P energy trading network under two different ESS ownership structures: user owned structure and a third party energy sharing provider (ESP) owned structure.…”

The authors in [38] investigated the optimal ESS operation and sizing problem in a P2P energy trading network under two different ESS ownership structures: user owned structure and a third party energy sharing provider (ESP) owned structure. The comparison of economic benefit between the two structures shows that the ESP owned model achieves a smaller energy cost saving owing to the fact that the benefits are split between the users and the ESP, but requires less investment on a smaller ESS, compared to the user owned ESS structure.…”

Real Time Energy Storage Sharing With Load Scheduling: A Lyapunov-Based Approach

2021

This paper studies energy storage sharing in a grid-connected residential microgrid, where a group of households with controllable loads and renewable generations cooperatively shares an energy storage. By exploiting delay tolerance of elastic loads, we develop a joint real time storage sharing and load management system that takes into consideration the operational constraints of the shared energy storage coupled with the time-varying load demands and stochastic renewable generations of all households, with the aim of minimizing the long term time-averaged energy costs of the households without reducing energy consumption. A Lyapunov-based online battery sharing control algorithm is designed to jointly optimize energy consumption, load scheduling and energy charging/discharging actions of individual households only based on current system states. The proposed online sharing algorithm enables the households to optimally utilize the shared battery and reschedule their delay tolerant loads in a distributed but coordinated fashion, while satisfying the time-varying energy consumption preference of each household. Numerical simulation results demonstrate that the low-complexity joint storage sharing and load scheduling algorithm serves the load demands of each household with a lower delay at a relatively low cost while facilitating a fair utilization of the shared energy among the households in terms of their energy contributions.

“…(2) The whole life cycle technical and economical study of energy storage is carried out. Some researchers use the financial analysis method of net present value (NPV) [20], investment payback period [21], and other indicators to study this problem. Some scholars use the methods of life cycle cost of storage (LCCOS) and leveled cost of energy (LCOE) [22] and cost-benefit analysis [23] to analyze and evaluate the economic performance of energy storage in a long time scale from the perspective of investors.…”

The combined cooling, heating, and power (CCHP) microgrid system is good for energy gradient utility. At the same time, it can promote the renewable energy (RE) consumption and abate environmental pollution. In a CCHP microgrid system, the electrical energy storage (EES), which can storage and release electrical energy, plays an indispensable role. A robust optimization model of the CCHP microgrid participating in power market transaction is constructed to calculate the CCHP microgrid operation cost in 4 cases. The results show that the EES can significantly reduce the cost of the CCHP microgrid by 13.21%, compared with 8.36% in Group 1 without renewable energy. The EES can reduce the reserved capacity of micro gas turbine units to deal with the precariousness of RE generation and then reduce the CCHP microgrid operation cost by reducing the purchase of energy from the power grid and arbitrage. Finally, the calculation method of comprehensive value of the EES is constructed. The comprehensive value of the EES is higher in Group 2 with renewable energy compared with Group 1 without renewable energy. Through net present value (NPV) calculation and sensitivity analysis, it is found that the RE penetration level and EES cost have the greatest impact on the economic performance of EES. This shows that with the continuous rising of the RE penetration level and the gradual decrease of EES cost, great potential still waits to be tapped in the comprehensive value of EES in the future.
