Analyzing the Technical Constraints of Single Phase Residential Grid-Connected Pv Under Net Energy Metering Scheme

Abstract

Integrating clean and sustainable energy sources into the conventional utility grid benefits both the environmental concerns and the economy. The net energy metering (NEM) scheme is convenient in this situation. After meeting the energy requirements of its associated loads, it integrates excess photovoltaic (PV) generation into the main grid, lowering the cost of massive battery storage and increasing the supply of clean energy to the grid. From the perspective of single-phase residential grid-connected PV systems, this can have beneficial repercussions in addition to the aforementioned cause. Integration of a single-phase distributive generation system, such as solar PV with the utility grid, introduces various concerns with power quality issues, including overvoltage, an increase in fault level and harmonics effect. This paper evaluates the effects of technical parameters on residential single-phase grid-connected photovoltaic integration with the IEEE 14 bus system. Matlab/Simulink is used to develop the system, which includes an IEEE 14 bus and a single-phase grid-connected PV module connected to the following bus with its associated residential loads. The effects of varied PV module sizing and load variation on the technical parameters are observed. The research findings are compared to the current models of residential three-phase grid-connected PV under the NEM scheme. The proposed sizing and mitigation of the system's impact by technical concerns are discussed.
