[Abstract]:As the main field of energy consumption and gas emission, power industry provides reliable guarantee for its sustainable development. Using clean energy to generate electricity is an important way to realize energy saving and emission reduction in power system. In the context of energy-saving scheduling and its extension, it is of great significance to study the optimal scheduling of clean energy access systems. This paper introduces in detail the structure and function of the energy saving dispatching simulation system of Guangdong power network, and uses the system to carry on the simulation calculation of the dispatching, analyzes the energy saving, economic, environmental protection and other scheduling effects. The definition of comprehensive energy-saving dispatching and the actual situation of Guangdong energy-saving dispatching mode, the connotation of energy-saving scheduling is analyzed from three aspects: saving fossil energy, reducing network loss and giving play to the substitution of renewable energy. With the development of power market and low carbon power, the concept of energy saving dispatching is expanded. In Guangdong energy conservation dispatching mode, hydropower plan and thermal power plan are compiled separately. In order to give full consideration to the connotation of renewable energy substitution, Aiming at the hydro-thermal power system, the models of hydropower peak shaving aiming at the minimum output adjustment quantity and the minimum fuel consumption of thermal power unit are established, and the thermal power peak shaving model aiming at the maximum power generation and the minimum fuel consumption of the system is established respectively. The simulation results show that the peak-shaving strategy can make full use of the peak-shaving ability of hydropower, and the thermal power peak-shaving strategy can play an effective role in the substitution of hydropower. More efficient use of hydraulic resources. In order to further explore the expansion of energy-saving scheduling under the low carbon background, a scheduling model with the aim of utilizing clean energy efficiently, ensuring the smooth operation of thermal power units and reducing system fuel consumption and carbon emissions was established for the Fengshui fire joint system. The numerical example shows that on the basis of fully absorbing wind power and reasonably using carbon capture unit, the wind water fire combined system can relieve the peak pressure of hydropower, and reduce the carbon dioxide emissions of the system on the basis of improving the efficiency of hydropower utilization. The energy-saving scheduling of the system with clean energy such as hydropower and wind power is studied, and the energy saving potential of the system is deeply excavated. By making a reasonable scheduling plan, the efficiency of clean energy utilization is effectively improved. And it has important practical significance to promote the popularization and application of energy saving dispatching.
