Modeling and Case Study for Regional Power Grid Operation with Variety of Power Plants

Simply stated the potential risks of the grid power system economic operation brought by a large-scale establishment of new energy. Faced with the problems of making the power grid coordination and efficient safe operation, and making it suitable for clean energy and distributed power systems, this paper establishes the model combined ultra-structure modelling and optimization of hybrid method, makes the program using GAMS software, and at last establishes the dynamic model of the power point coordinated control in a regional smart grid, which contains conventional and new energy and pumped storage power station. Beside, make a case of Hebei South Power Grid, deduce coordinated operation of different power point control strategy of Hebei South Power Grid. Point the basic ideas and guidelines for regional grid coordination of various power control strategy for running.

China Oil Price-GDP Elasticity Coefficient and Optimal Strategic Petroleum Reserve Scale Analysis

The rising international oil prices will cause the loss of national GDP and the establishment of strategic petroleum reserves (SPR) could avoid this loss as much as possible. The oil price-GDP elasticity coefficient is an important parameter in calculating strategic petroleum reserve, but since it is difficult to obtain, it is also hard to calculate. This paper provides the fitting formula of oil price-GDP elasticity coefficient based on the regression analyzing of literature data. China’s oil price-GDP elasticity coefficient in recent years has been analyzed and predictions for future trends in different situations have been made. Finally, the predicted oil price-GDP elasticity coefficient is used to calculate the size of Chinas strategic petroleum reserve and its earnings.

Development Scale Analysis for Coal Derived Synthetic Natural Gas (SNG) under China Energy Security

Natural gas plays an important role in industry, transportation and electric power. The first of all problems to solve is to ensure energy security while meeting the demand for gas. Through analyzing the connotation and the frame of energy security, it clears about the significant of the security of energy and gas supply in China, and sets up the benefits and losses model of natural gas, analyzes the loss of economic cost and the obtained economic benefits based on the process of SNG to protect natural gas security. By analyzing the case, the results show that there exists a most advantage point between the loss of economic cost and the obtained economic benefits in the process of natural gas security, China could develop SNG scale of 50 billion cubic meters production by the end of 2030, at this time, it will get the maximum net income of nearly 5 billion RMB. In addition, the results show that the two most important parameters which influence the profits and losses are energy consumption GDP elasticity coefficient and the nature gas price in the process of SNG guaranteeing natural gas security.
