“…From a technical point of view, the idle state of the battery (fully charged) made this export inevitable. Nonetheless, the active feed-in power is also beneficial for the grid in terms of reduced transmission losses and lower investments in new utility generation units [77]. On the contrary, the winter profile exhibits dissimilarity in terms of load consumption, PV generation capacity, and grid usage.…”

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.

“…In the case of solar energy consumers often know in advance that their investments can produce energy only during the daytime. A solar system has a constant power output, the system only needs to be sized larger and it's needed for excess energy storage system [6][7][8]. There are 3 emerging storage technologies that is viable energy solution for renewables such as solar or wind in recent scenario such as 1.…”

The demand for sustainable energy has increased significantly over the years due to the rapid depletion of fossil fuels. The solar photovoltaic system has been the advantage of converting solar irradiation directly to electricity, and it is suitable for most of the regions. But in the case of solar energy conversion, the voltage evolved from the solar photovoltaic cells is not adequate to meet the energy demand. Therefore, the converters and inverters with energy storage systems are used to fulfill the energy demand. These conversion architectures create new challenges for effective management of the grid. Due to the evaluation of power generation, load in a particular region or area, let us simplify with the help of the duck curve. The study is focused on the energy auditing, assessment, and measurement of solar irradiation from PV system design software. This graphical representation is implemented with a typical electricity load pattern at any region.

“…In this paper, the operation of the PV system in a grid supporting mode is discussed. At present, the impact of grid integration of PV systems is widely researched, but the effect of grid faults on PV systems and their influence on grid supporting nature of PV inverters is relatively under evolution . The most frequent and serious issues that affect the operation of grid‐connected PV systems are the power quality issues, voltage sags, swells, and faults .…”

Summary Large photovoltaic (PV) penetrations into the electric grid resulted in new challenges such as reverse power flow and violation of voltage profile. The traditional methods for voltage regulation in a grid‐connected PV system are hardly adaptable to these changes as they only contain the local information which is used without the knowledge of how the control action affects the overall system. To address this problem, this paper extends the reactive power control capability of solar PV inverters by combining them with static power electronic devices for regulating voltage during grid faults. For efficient identification of grid faults, a support vector machine‐based fault classification mechanism is developed. The proposed method prioritizes the reactive power control using PV inverter by adapting a predefined hierarchical control structure. The complete methodology is realized by testing it with a two‐stage single‐phase grid‐connected PV system. The experimental results verify the accuracy of the classification algorithm and depict the effectiveness of the proposed controller in both under and overvoltage situations.
