Application of DC-AC Hybrid Grid and Solar Photovoltaic Generation with Battery Storage Using Smart Grid

Abstract

Smart grid for the past few years has been the prime focus of research in power systems. The aim is to eliminate load shedding and problematic blackout conditions, further offering cheap and continuous supply of electricity for both large and small consumers. Another benefit is to integrate renewable energy resources with existing dump grid in more efficient and cost-effective manner. In past few years, growing demand for sustainable energy increases the consumption of solar PV. Since generation from solar PV is in DC and most of the appliances at home could be operated on DC, AC-DC hybrid distribution system with energy management system is proposed in this paper. EMS helps to shift or control the auxiliary load and compel the users to operate specific load at certain time slots. These techniques further help to manage the excessive load during peak and off peak hours. It demonstrates the practical implementation of DC-AC network with integration of solar PV and battery storage with existing infrastructure. The results show a remarkable improvement using hybrid AC-DC framework in terms of reliability and efficiency. All this functioning together enhances the overall efficiency; hence, a secure, economical, reliable, and intelligent system leads to a smart grid.

Review of carbon dioxide (CO 2 ) based heating and cooling technologies: Past, present, and future outlook

“…The growing electrical demands, diminishing fossil fuels, and environmental pollution can be alleviated by the use of energy storage and renewable energy technologies . Renewable energy resources are gaining popularity due to a shortage of energy supply and its utilization, growing concerns about global warming, and environmental pollution . Among the pollution‐free energy sources, solar energy has emerged as a competitive technology, besides different types of challenges, in those areas with good persistence factor during the day.…”

“…16,17 Renewable energy resources are gaining popularity due to a shortage of energy supply and its utilization, growing concerns about global warming, and environmental pollution. [18][19][20] Among the pollution-free energy sources, solar energy has emerged as a competitive technology, besides different types of challenges, in those areas with good persistence factor during the day. Solar heating and cooling is the best solution for achieving high heating and cooling demands throughout the world.…”

Microcontroller-Based Strategies for the Incorporation of Solar to Domestic Electricity

“…A multi-control single-input switch was used to select between diesel, wind and photovoltaic sources in [13]. PV energy was integrated to the smart grid system by using energy management systems that shifted load connections from one energy system to the other during certain time slots [14]. Fuzzy logic was also used to manage energy consumed by loads as means of reducing electrical bills [15].…”

Optimum Configuration of Solar PV Topologies for DC Microgrid Connected to the Longhouse Communities in Sarawak, Malaysia

“…In the typical DC microgrid system, a house in the village generally consumes about 100 -150 W; its load mostly consists of multiple DC fans, LED, or DC light bulb and a DC-AC converter or inverter for other electrical appliances. A low DC voltage (12 or 24) is normally used for lower power applications [13,14,19,28]. It should be noted that the loads in the villages of Sarawak normally consist of lighting systems and low-power apparatus.…”
