The residential energy scheduling of solar energy is an important research area of smart grid. On the demand side, factors such as household loads, storage batteries, the outside public utility grid and renewable energy resources, are combined together as a nonlinear, time-varying, indefinite and complex system, which is difficult to manage or optimize. Many nations have already applied the residential real-time pricing to balance the burden on their grid. In order to enhance electricity efficiency of the residential micro grid, this paper presents an action dependent heuristic dynamic programming(ADHDP) method to solve the residential energy scheduling problem. The highlights of this paper are listed below. First,the weather-type classification is adopted to establish three types of programming models based on the features of the solar energy. In addition, the priorities of different energy resources are set to reduce the loss of electrical energy ***, three ADHDP-based neural networks, which can update themselves during applications, are designed to manage the flows of electricity. Third, simulation results show that the proposed scheduling method has effectively reduced the total electricity cost and improved load balancing process. The comparison with the particle swarm optimization algorithm further proves that the present method has a promising effect on energy management to save cost.

Dairy industry is an indispensable component of modem agriculture. How to improve informatization level and technology content of dairy industry and progress informationalization construction process of pastures has been one of the most popular topics in development of dairy industry in China. Compared with the countries with developed dairy industry worldwide, dairy industry in China is featured by not high informationization level and backward modernization level at the present stage. However, development and maturity of related technologies for pasture informatization construction provides a significant opportunity for transformation and upgrading and leaping development of dairy industry in China.
