[Abstract]:With the shortage of traditional energy and the increasingly serious environmental pollution, renewable energy development has a broad application prospect. At present, there are still many island areas in our country without electricity or electricity. Ocean energy complementary independent power generation system can take advantage of the rich marine energy in the island area to meet the electricity demand of this part of the population without electricity. In addition, from a long-term perspective. Develop large-scale ocean energy multi-energy complementary independent power generation system, establish regional power grid, step by step replace traditional energy sources. It can solve the energy crisis and environmental problems to a certain extent. With the gradual development of multi-energy complementary power generation system, the requirements of its control technology are becoming higher and higher. Good control technology can promote the development of multi-energy complementary independent power generation system.

According to the characteristics of marine energy and other renewable energy, based on the genetic algorithm theory, a multi-energy complementary independent power generation system power allocation model is established, and the economic model is used as the objective function. The field installation condition, resource complementary characteristic condition, power supply and load matching constraint condition are analyzed. The optimal configuration of power supply, energy storage and load is obtained by taking the resource and load situation of big pipe island as an example. 3. The control strategy of marine multi-energy complementary independent power generation system is analyzed in detail, including the following: 1) analyzing three ways to realize the energy management and control strategy of the system, that is, controlling the energy storage system, the wind power system, and the load switching to realize the energy dispatch management. The energy flow of the system is analyzed in detail. The closed-loop voltage-mode PWM control strategy is designed. Under the condition that the input voltage is fluctuating, the closed-loop voltage feedback loop is constructed by using the PID controller and PWM control. The stability of output voltage of Boost converter circuit is guaranteed. The control simulation of Boost circuit using MATLANB/Simulink is carried out, and the simulation results show that. The closed-loop voltage mode PWM control strategy has good control effect. 3) the control strategy of constant voltage and current limit charge and discharge, the control strategy of packet management and their respective implementation methods are formulated, and combined with different system structures, the strategy of packet management control is analyzed, and the simulation analysis is carried out. 4. The controller suitable for island environment application is designed. According to the proposed control strategy and practical application conditions, the hardware and software equipment of the controller are selected, and the hardware of the controller is carried out according to the characteristics of the island environment. The software and anticorrosion design have realized the control function and the related protection function, and provided the technical support for the design of the multi-energy complementary independent power system controller.
