Research On Economic Dispatching Of Power Grid Based On Particle Swarm Algorithm

The development level of electric power industry is an important symbol of a country's economic development.Electricity plays a very important role in our national economy,is an important foundation for the development of national economy,and is also an important industry in the development strategy of national economy.Since the 13 th Five-Year Plan,China's economy has been developing vigorously,and the demand for electricity from all walks of life is increasing.Therefore,under the basic premise of guaranteeing the supply of electricity,we should also improve the quality of power,the economy of power grid operation and the impact on the environment in the process of power generation.Electric power dispatching,that is,load distribution of power grid,is currently completed by computer.So different algorithms will affect the final result of load distribution.A good performance algorithm not only increases the economic benefit of the whole power grid,but also reduces the environmental pollution caused by fossil fuel combustion in traditional power grid.Traditional economic dispatching is a system optimization aiming at reducing the cost of power generation.With the concept of sustainable development being put forward and developed,reducing the environmental problems caused by power generation has attracted wide attention of government departments and scholars.The government advocates the construction of a resource-saving society,and proposes energy-saving dispatching to limit the emission of polluted gases from thermal power plants.Therefore,in electric power dispatching,the government advocates the construction of a resource-saving society.At the same time,power generation efficiency,power generation cost,energy consumption and its pollution to the environment need to be considered to minimize environmental pollution,that is,to reduce emissions.Energy conservation is an important guarantee for sustainable economic development in China.It is of great practical significance to study the economic dispatch of unit load in thermal power plants.In view of the actual operation situation of thermal power plants,this paper first studies the energy consumption characteristic curve of units in detail,establishes the mathematical model of load optimal distribution and unit economic combination,and considers multiple constraints in combination with the economy and security of unit operation,discusses the economic dispatching problem of thermal power plants from the aspects of system model and algorithm,and compares the advantages and disadvantages of these models.The advantages and disadvantages of the algorithm are described in terms of search speed,accuracy and convergence.Based on the traditional algorithm,the algorithm is improved to make the improved algorithm have better search performance.The Pareto optimal frontier feasible solution is obtained by calculation,and compared with the references.It is proved that the algorithm has better effect..
