Concrete is one of the most widespread construction materials in the world, but its production is responsible for significant amounts of energy consumption, and even greater greenhouse gas emissions. However, the substitution of Portland cement with fly ash (FA) reduces both the energy consumption and the greenhouse gas emissions generated during the production of clinker. Currently, most studies...
Combining actual demands for ultra-high voltage (UHV) power grid of our country electricity production, power collection, electricity transmission and distribution, functions, adequacy and reliability of different UHV power grid projection are discussed in this paper. They were discussed that differences in function and reliability of different UHV power grid structure, and the development necessity,...
A hybrid approach based on the pseudo-sequential sampling and the network-equivalence techniques is proposed for distribution system reliability evaluation in this paper. In pseudo-sequential sampling, a failure state is obtained based on the non sequential simulation at first, then the whole system interruption I(a set of successive failure states) is acquired by the forward/backward simulation associated...
One of the most important issues in the development and utilization of wind-based distribution generation is to quantify the impact of wind power on distribution system reliability. This paper proposes how to deal with wind generators connected to sub-feeders of distribution system in reliability evaluation by means of the network-equivalent approach. The random nature of wind power, which is quite...
