The Study Of Light And Water-Energy Co-Generation Of Complex

In this paper, a detailed study of distributed generation technologies on the impact of regional power grids. Focusing on the geography of the Jinhua area. This area lacks of oil, coal and other mineral resources, and the resources of thermal power generation. This area lacks of large river and the corresponding water resources. in the existing extreme lack of power grid architecture, regional load networks for more than 90% rely on, is not conducive to hierarchical partition scheduling in place the principle of balance, making the supply and demand is very prominent. The photoelectric, wind power is very suitable for distributed power represented by the characteristics of the region, can provide some of the output power to reduce the regional power grid of the provincial network, or even East China Power Grid dependence and reduce accidents.Collecting a month data of weather and the electricity from Zhi yan PV power station. Be based on these data and the features of small hydropower in Jin hua grid more than other girds, analyzes the use of existing hydropower and photovoltaic solar power generation joint operations to smooth the mutation caused by accessing to grid, additional reactive power, stability, access point node voltage. Through designs optimal strategies to enhance the utilization of photovoltaic power generation, to reduce the impact of photovoltaic power generation uncontrollability, intermittent problems on the Power Grid. According to real-time characteristics of load which adjust the output power of the hydropower to stabilize the system of supply and demand balance.For example, analyzes the data of water flow and light intensity in An di station by 2009 year, to calculate hydropower and photovoltaic solar power generation combined operation scheduling strategies. By optimal strategies compensate for the distributed power generation technology level deficiencies, optimize network structure, rational use of resources. Using PSCAD software for joint operation of hydroelectric and photovoltaic power generation is simulated. Finally, genetic algorithm simulated in the distributed power grid power jointly with the traditional operation, according to the strategy were calculated using the power to find the minimum cost strategy.
