Distributed Power

In distribution networks with distributed power supplies, distributed power supplies can also be used as backup power sources to support the grid. If a distribution network contains multiple distributed power sources, the distribution network becomes a complex power grid with multiple power supplies. When a short-circuit fault occurs at a certain point on the power distribution network, the size, direction and duration of the short-circuit current are no longer single due to the existence of distributed power, and will vary with the location and capacity of the distributed power supply system. The change, in turn, affects the current in the grid, resulting in the generation and propagation of additional current. This power grid of power electronics will cause problems such as excessive standard mis-operation, abnormal heating of the converter and component burnout, and communication system failure. It is of great and practical significance to study the influence of distributed power in distributed power distribution networks.

System Power

The Distributed Generation can enhance the system power supply reliability and alleviate the pitch peak and restricted transmission capacity caused by large-scale wind power grid connection and other problems. In Fuxin, the system power supply is inadequate; the wind power integration is restricted and there are rich wind power reserves. Based on the current situation, this paper analyzes the necessity and feasibility of developing the distributed wind power in Fuxin and provides advisory opinions on the development sites and mode of wind power generation.

The Impact

In recent years, there was a rapid development of wind power. The impact of large amount of wind power integration into power system on the voltage and power quality could not be ignored. The characteristic of internal dynamics of wind turbine was complicated, as a result, it could not be simulated by electromechanical transient simulation soft (BPA). It was necessary for transformation from BPA to PSCAD which was electromagnetic transient simulation program. However, the modeling work for the external power grid was enormous and meaningless. In this paper, external network was equivalent based on the BPA data of actual grid combined with PSCAD. This method not only could simulate the influence both simple and effective, but also could establish the detailed model of the regional power grid and wind power. At the same time it has been effectively used in the analysis of wind power integration into actual wind projects of Fujian power grid which achieved very good results.

In-situ exploitation of oil shale by electric heating consumes large amounts of electricity. Under the existing dispatch system, using wind power output and photovoltaic power output to support the exploitation of oil shale can promote renewable energy use, reduce the consumption of coal and other fossil fuels, and protect the environment from pollution. In this study, the characteristics of the wind power and photovoltaic power output are analyzed, and the correlation between the power outputs is evaluated using the copula function. The load of exploiting oil shale is presented. In order to match the heating load characteristics of oil shale exploitation, a particle swarm optimization algorithm is used to optimize the heating temperature of the heated well to minimize the cost. An economic analysis is conducted of five different power supply combinations, including wind power, photovoltaic power, and the existing power grid. The income ratio of the five modes is calculated using actual data of a project in Jilin province in China, and the feasibility of in-situ electric heating by wind power, photovoltaic power, and the power grid is determined. The results of this study provide useful references for decision makers to plan the power supply scheme for in-situ oil shale exploitation.
