Considering the fact that the optimal operation of micro grid is an economic dispatch of a dynamic system, the study investigates the establishment of the dynamic optimization model for optimally operating micro grid and attempts to solve the model. In view of the significance of the economic operation, for optimally determining the power outputs of each micro source and the power import from/export...
Microgrid is an effective system for integrating distributed generations, energy storages, loads and some auxiliary devices. To improve the efficiency of the system, the optimal energy dispatch is an effective method that can control these kinds of sources and loads. A real-time optimal energy dispatch for microgrid is proposed in this paper, which can reduce the energy loss and enhance the economy...
This study presents an application of Nondominated sorting genetic algorithm II (NSGA-II) to the multi-objective optimal placement of distributed generation (DG) in distribution system with special requirements for power quality and power supply. To effectively replicate different perspectives and satisfy some consumers' special requirements, a multi-objective optimization model, which considers technical,...
In this paper, the coordinated development evaluation index system and model of regional Science&Technology and economy system have been put forward. At the same time, for example of Heilongjiang province, the development status of Science&Technology and economy system in Heilongjiang province has been evaluated. Finally, some advices have been given based on the demonstration research.
This paper analyses the development status of Tianjin tourism industry, the factors restricting and the importance of the development, expounds that the development of Tianjin tourism should return to its original culture and the important influence of Haihe river culture, clarifies that to Haihe river as the carrier, combine the Haihe river culture with the tourism industry in the new era, establish...
