In the condition of large scale wind power connection, the uncertain of the wind power output takes great challenge to the peak regulation. In this paper for some wind power connection system, the influence of wind power connection to the peak regulation was studied by analyzing the system load and the historical real data after the wind power connection. The computation model which evaluates the normal units’ anti- peak adjusting capability was built and the multiply integer program algorithm was used to solve this model. A real case was used to test the exactness and feasibility of the computation model.

This paper presents a vehicle dynamic model of 7-freedom degrees with different road adhesion coefficients based on MATLAB/Simulink platform. The correctness was verified by the dynamic simulation of vehicle model with the same parameters established in CarMaker software. In order to reduce the torque of the slip wheel to make full use of the road adhesion as well as to regulate the torque of non-slip wheel to ensure the stability of the vehicle, the control strategy of driving anti-slip control system with stability torque adjustment function working in full speed range was designed. In terms of torque distribution, according to different four-wheel slip state, it was proposed to different stability torque adjustment mode. The controller model was set up, and the closed-loop simulation of docking and split-road surface were carried out. The effectiveness of the anti-slip control and the torque control strategy are verified based on the simulation platform.

Backsheet is the key element to ensure the power generation of PV modules during their whole life cycle. To continually decrease the LCOE, backsheets of new structures are gradually applied. Currently, the evaluation of module product performance is mainly on the module scale, while the assessment of each single material is rare. This paper is aimed at the evaluation of each single backsheet’s reliability when applied in different climatic environments for the widely used new backsheet structures (BS1-BS5). Through comparative research, the backsheet based on thicker PET was found to have a better mechanical performance and BS3 exhibited good resistance performance in hot and humid condition, which could be attributed to the low water vapor transmission rate of the PO film.

In this paper a line fault probability calculation method by the combined effects of icing and wind is developed. Considering the force effect of icing and wind on the transmission lines, an icing-wind load is presented. It can be used to calculated the real-time or predict line fault probability using the characteristic exponential model reflecting metal resisting capacity. The example using historical meteorological data and simulating grid is given and the results show that, icing-wind load presented in this paper makes the calculate result of failure probability more serious. The line fault probability is helpful for the further grid security control.
