This paper applies the hosting-capacity method to a realistic distribution system. Under given circumstances the hosting capacity for Distributed Energy Resources (DER) identifies the degree of DER in power grid that can be accepted without endangering the reliability or quality of power. In this case study two limits setting the hosting capacity were evaluated: overvoltage and overcurrent. Finally...
The northeast region of China is an important industrial base and an area with abundant wind energy resources. Therefore, it holds an important strategic position in both exploitation and utilization of wind energy resources and wind power industry development in China. This article assessed the wind resource reserves in the northeast region and their exploitable value, and analyzed the current state...
Africa has abundant wind energy resources, and consumption of conventional energy will continue to grow with economic and social development, an urgent need for abundant renewable energy, and particularly abundant wind power resources as a new energy. Africa is copying the model and path of Western countries for wind power development, which will certainly increase the price of wind power equipment...
In India the installed capacity of wind power generation is almost 7% and about 2% of total energy is from wind. Despite turning out to be a boon, wind power generation is still perceived to be power system unfriendly; even in the present scenario of peak power demand shortages as well as energy shortages. The case studies presented here indicate as to how wind energy could on the one hand be termed...
This paper analyzes the rural area's wind energy and sunlight resources in China by means of research and study about wind energy and light energy resources. An independent power supply system which complemented each other by wind and light is prompted here, and the system suits for most rural areas in China. This paper also introduces the design of the system about its basic structure and autocontrol...
Wind power generation has developed fast in recent years, which not only alleviate the press of power energy, but also give the promotion of sustainable development for environment. China is rich in wind energy resources. The development of wind power in china has made marked progress, although there are some problems. This paper elaborates the importance of the development of wind power; provides...
For the sake of wind energy exploitation, the Fifth Generation Mesoscale Model (MM5) has been applied to downscale 2.5deg reanalysis data provided by the National Centers for Environmental Prediction (NCEP) and the National Center for Atmospheric Research (NCAR) onto a 3.3-km grid covering the fuel-poor Jiangsu Province for the three representative years, 1972, 1997, and 2000 respectively. The simulated...
Przedstawiono wstępne wyniki badań dotyczących zasobów energii wiatrowej na terenie Rolniczego Zakładu Doświadczalnego SGGW w Żelaznej k. Skierniewic (woj. łódzkie). Obliczenia oparto o pomiary prowadzone na polowej stacji meteorologicznej Katedry Podstaw Inżynierii.
