Based On The Theory Of Complex Adaptive Systems Power Structure Optimization

The power industry has been committed to achieving clean and low-carbon power generation.At present,new energy power generation such as photovoltaic power plants and wind farms are increasing in the power system.Compared with traditional power sources,new energy power generation has low carbon emissions.With the increase of grid-connected capacity,the impact of photovoltaic and wind power on the system becomes more and more obvious.New energy has the characteristics of intermittent,volatility,reverse peak shaving,and poor controllability,so it is necessary to change the traditional power planning method.The scientific and reasonable allocation of clean energy capacity such as wind power and photovoltaic is not only an important prerequisite for giving full play to the comprehensive benefits of the multi-energy power system,but also an indispensable link in promoting the construction of clean energy grids at this stage.Therefore,this paper establishes a multi-energy power planning model based on the Complex Adaptive System Theory(CAS).Aiming at maximizing economic benefits,the ratio of each capacity is solved and the production simulation is carried out.The main tasks are as follows:(1)Conducted certain research on the theory of complex adaptive system,analyzed the possibility of applying complex adaptive system theory to the power system,analyzed the power system from the perspective of complex adaptive system,and compared and merged the two.(2)Established a multi-energy sequential stochastic production simulation method including wind power,photovoltaic,hydropower,thermal power,solar thermal and energy storage.In order to retain the time sequence characteristics of the power system,based on the equivalent electric quantity function method,each hour is used as the simulation step to calculate the system operation indicators at each time during the simulation period.Finally,the stochastic production simulation calculation of the actual power system in a certain province of our country verifies the effectiveness of the proposed method.(3)Aiming at the multi-energy power system,this paper proposes a power planning model based on the theory of complex adaptive systems.The model uses six types of power sources: wind power,photovoltaic,hydropower,thermal power,solar thermal,and energy storage as the adaptive main body to build the main body.Model,stipulate its behavioral rules,power supply capacity as the decision-making quantity,take the maximum economic benefit as the objective function,reasonably configure multi-energy power supply capacity,and adopt multi-energy sequential stochastic production simulation method for production simulation,and finally carry out with genetic algorithm Compare,verify the effective applicability of the proposed model and algorithm.
