For present distribution transformer failure rate prediction model, load and weather forecast information in the future have been not considered. In this paper, distribution transformer failure rate prediction model with parameters is proposed. Firstly, the characteristics of several common failure rate models are analyzed. The failure rate model combined the health index and operating time is established...
With photovoltaic technology development and application of the expansion of photovoltaic, the accuracy of power generation forecast will directly affect the grid load frequency, grid stability, system reliability, power quality, investment and the system operating efficiency. The short-term forecasting research of photovoltaic power generation will help to stabilize power system operation, to optimize...
Being photovoltaic power generation affected by radiation strength, wind speed, clouds cover and environment temperature, the generating in each moment is fluctuate. The operational characteristics of grid-connected PV systems is coincided with gray theory application conditions. A gray theory model has been applied in short-term forecast of grid-connected photovoltaic system. The verification model...
Power structure optimization is to determine the planning time, the type and the capacity of power supply, thus the best way to meet the load demand for development. With the help of Markov decision-making process (MDP), it has been established based on the grid-connected PV system generation. Using the optimal strategy of MDP, one step transition probability matrix and the expected total reward criterion...

With renewable energy generating rapid growth, multi-power structure optimization problem with the grid-connected PV power has been a cause of concern. This paper presents Markov decision-making process (MDP) conditions, optimal dynamic programming strategy, N-stage total expectation reward criteria and total expectation cost of MDP model in multi-power structure optimization with grid-connected PV...
