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 transmissions.Second, 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.展开更多

The children of today will run the families of the 21st century. Their survival, protection and development decide, for the most part, the quality of a people and lay the foundation of human progress as a whole. The 1990 World Summit for Children endorsed the "World Declaration on the Survival, Protection and Development of Children" and the "Plan of Action for Implementing the World Declaration on the Survival, Protection and Development of Children in the 1990s," (hereinafter referred to as "Declaration" and "Plan of Action" for short), In March 1991, Premier Li Peng signed the two documents on behalf of the Chinese Government, making a solemn commitment to this major undertaking. 2. The wholesome development of children has a bearing upon the future of China. The Communist Party of China and the Chinese Government have always paid close attention to the survival,展开更多
