This paper presents a day-based stochastic unit maintenance schedule (UMS) model for power producers to optimize their payoffs, considering the uncertainty of market prices. In the proposed model, the producer's benefits include the expected energy-selling profits in energy market and maintenance costs in each period. An effective Monte Carlo simulation based on latin hypercube sampling (LHS-MC) is adopted to evaluate the related risk associated with uncertain energy prices. Then, the proposed UMS issue can be solved via a combination of genetic algorithms and linear programmings. Finally, numerical examples on a four-unit producer are utilized to illustrate the usefulness of the presented scheme. [ABSTRACT FROM PUBLISHER]

This paper analyzes the demand of unmanned helicopter power line inspection system, and the detection range of camera is researched in detail. Johnson calculation criteria is used to calculate the suitable CMOS pixel dimensions and the focal length of lens. According to the calculation results, extensive experiments for camera payload were done using the unmanned helicopter. The dimensions of the CMOS camera and the focal length of lens were verified. We chose the suitable camera and lens by the experiments. [ABSTRACT FROM PUBLISHER]
