An Overview of the current challenges and Issues in Smart Grid Technologies

Smart grid (SG) will transform contemporary businesses by offering efficient solutions to improve existing power systems' efficiency, stability, and resilience. SG provides long-term power supply by interconnecting electrical grids and communications infrastructures. However, SGs are plagued with problems and complexities, particularly regarding capacity, reliability, and security. The main concerning issues for consumers are data breaches and malicious hacking of personal equipment. In addition, the growing integration of distributed generation (DG) and electric vehicles (EVs) has exacerbated the problem in numerous ways, including synchronization challenges, voltage regulations, malfunctions, and harmonic components in current and voltage waveforms. This paper examines the challenges and issues associated with SG, such as communication, security, energy integration, and power quality.
