“…For example, the loading of the substation transformer at 8 pm reached the value of 78.8% prior to ESSs engagement, while when the ESSs injected power into grid, the loading level was reduced to 63.3% at 8 pm.

This work examines the effect of energy storage systems (ESSs) operation on the voltage stability and quality of the local power system. The variation of these two voltage dimensions is expressed in a collective manner by the novel voltage stability and quality index (VSQI). For the calculation of the VSQI , a complete voltage stability curve is required, and the coordinates associated with voltage stability and quality are identified. The distance between the abovementioned coordinates, that collectively indicates the effect of ESSs operation on the two voltage dimensions, is represented by the VSQI. The process for VSQI identification is repeated for each operating scenario, with the studied cases including grid operation prior to ESSs utilisation, grid support performed by a community level ESS, and grid operation with distributed ESSs. The ESSs are powered by renewable energy sources (RESs), and a future scenario of 70% photovoltaic (PV) penetration was examined. Other ESSs applications presented in this work, include time-shifting of the energy produced by RESs, peak load shaving, and reducing the loading levels of transmission lines and of the substation transformer. The above stack of ESSs applications, highlights the multifunctional role of ESSs as support to the grid. A real low voltage (LV) distribution network located in southeast Queensland, Australia was employed for the study.

Solar photovoltaic-based microgrid hosting capacity evaluation in electrical energy distribution network with voltage quality analysis

et al. 2021

In this paper, solar photovoltaic hosting capacity within the electrical distribution network is estimated for different buses, and the impacts of high PV penetration are evaluated using power hardware-in-loop testing methods. It is observed that the considered operational constraints (i.e. voltage and loadings) and their operational limits have a significant impact on the hosting capacity results. However, with increasing photovoltaic penetration, some of the network buses reach maximum hosting capacity, which affects the network operation (e.g. bus voltages, line loading). The results show that even distributing the maximum hosting capacity among different buses can increase the bus voltage rise to 9%. To maintain the network bus voltages within acceptable limits, reactive power voltage-based droop control is implemented in the photovoltaic conditioning devices to test the dynamics of the network operation. The results show that implementation of the droop control technique can reduce the maximum voltage rise from 9% to 4% in the considered case. This paper also presents the impact of forming a mesh type network (i.e. from radial network) on the voltage profile during PV penetration, and a comparative analysis of the operational performance of a mesh type and radial type electrical network is performed. It is observed that the cumulative effect of forming a mesh type network along with a droop control strategy can further improve the voltage profile and contribute to increase photovoltaic penetration. The results are verified using an experimental setup of digital real-time simulator and power hardware-in-loop test methods. The results from this work will be useful for estimating the appropriate photovoltaic hosting capacity within a distribution network and implementation of a droop control strategy in power conditioning devices to maintain the network operational parameters within the specified limits. Highlights Voltage and line loading constraints’ combination can reduce PV hosting capacity by 50% as compared to only voltage as a constraint. Implementation of reactive power versus voltage droop control in PV power conditioning device can reduce voltage variation from 9% to 4%. In a PV integrated electrical energy network, line loading can be reduced by 20% if the network is configured from radial to mesh type.

Battery energy storage systems (BESSs) are being presented as a prominent solution to the various imminent issues associated with the integration of variable renewable energy sources in the distribution system. Performance of grid‐connected BESS depends on the type of application (power and energy), grid operating parameters and level of interconnection point, which shows the necessity of benefit assessment of BESS technology and its applications in terms of economic and grid operations before investment at a larger scale. In this study, real‐time analysis and evaluation of two different battery technologies connected in a medium voltage (MV) distribution system are carried out. The main objective of this paper is focused on the impact analysis of large‐scale BESS on MV distribution feeder. A real case of installation of lithium‐ion and advanced lead‐acid battery systems into the Indian distribution system has been considered for this study. Different operational strategies of BESS such as frequency regulation and energy time‐shift have been performed with real‐time data. The effectiveness in usage of BESS with these functionalities has been verified in terms of peak shaving, improvement in voltage profile and reduction in power losses in the feeder.
