Smart Grid is one of the hot research directions of power system. How to interconnect the new energy power generation with power system safely and reliably is a major challenge in the development of Smart Grid. New energy power generation interconnection standards are the technology base, which will push the development of smart grid. This paper compares the photovoltaic power generation interconnection standards of home and abroad mainly. It points out the inadequacy of existing standards and that the photovoltaic power generation interconnection standards should focus on power quality, protection and control. This paper can be provided as a reference to improve existing standards and establish interconnection standards of other form new energy generation.

A solar-wind hybrid system plays a key role in power generation and becomes very important role to smart grid power systems. Also, the wind-solar hybrid energy storage control systems in coordination of energy markets, made economical to the electrical power system power system. Hybrid renewable energy system connected micro-grid consists of significant identification; in view of solve the rising electrical energy demand. In addition to this the problem of harmonic distortion in micro-grids due to the non-linear loads is an indispensable topic of study. Also, it is very significant for the better understanding of the power quality impacts in micro-grids. This paper presents detail analysis of different control techniques for optimization of harmonics in smart grid system and enhancement in power quality of the smart grid system. The performance of the control system is verified through the MATLAB simulation of the hybrid solar-wind electrical energy system.

With the development of wireless communication technology and computer technology, more and more smart technologies have been applied in electricity distribution networks. This paper presents an adaptive current differential protection and fast auto-closing system for application in 10 kV distribution networks in China Southern Power Grid. The current differential protection can adaptively change its settings according to the topology change of the primary distribution networks, thus the system effectively reduces the operation and maintenance cost of the power distribution network. In order to restore the power supply for the healthy part of the 10 kV networks quickly after a power system fault is cleared, the protection and control system provides wide area control function for automatic fault isolation and automatic switching. The traditional overcurrent protection and control system have no fault location function, it may take several minutes or even hours to manually locate a fault and then restore the power supply. Compared with the protection and control system of the traditional 10 kV distribution networks, the system developed can locate and isolate faults within 900 ms (assuming that the operating time of the load switch is 700 ms), and can quickly restore power supply in less than one second after a power system fault is cleared.
