| 内容記述 | Nowadays the world is facing energy crisis and the destruction of the global environment, fossil energy with highC紅hon emission will be gradually replaced by renewable energy with low carbon emission. With the economicdevelopment and social progress, the traditional power generation methods can no longer meet the requirements oftoday's power users fur the reliability and stability of electricity. Micro-grid, which provides lectricity and thermalenergy to the region with distributed power sourc邸such as wind, solar, storage, micro gas turbine, fuel cell andenergy storage systems, can effectively improve the quality of electricity and clear energy consumption, enhance thesecurity and stability of the grid, alleviate the energy crisis and reduce environmental pollution, and even increasethe financial income in the local area. Although microgrid systems are a hot topic in the power sector, the optimalscheduling of distributed micro power sources in micro grids is still a complex technical problem, and the randomvolatility of wind and solar power generation also poses certain safety risks to the microgrid itself. This means thatmicrogrids not only need to realize flexible and efficient application of distributed ener四at the level of low-voltagedistribution system and的Ive the problems of seamless access and grid-co皿ect.ed operation of large and diversedistributed energy sources, but also need precise, intelligent, flexible, safe and reliable energy management andmonitoring. The rapid development of information technology makes all this possible. This thesis, starting fromdistributed power supply. the relationship between the placement of photovoltaic panela and power generation isstudied. It is found that the M·shaped arrangement of solar panels reduces theゎtal power generation. However,the difference between the two becomes sm叫er as the latitude of the placement location decreases. Aa the latitudeinreases, the area used by the M·shape decreases significantly. Then the difference between S- and M·shape powergeneration is compared from the resident.a'consumption. In off-grid operation, S·shape will outperform M-shape,but the difference is small with minimal affect. In grid-connected operation, the difference between the two isessentially the same after a household electricity strategy is developed using the PSO op止平zation algorithm. Thenan optimal operation model based on electric vehicle charging stations is also developed in the thesis. Using theMILP optimization algorithm, the optimal dispatching strategy was developed. The advantages and disadvantagesof the dispatching strategy in the micro grid will directly affect the economy of micro grid operation and the reliabilityof power supply, and it has important theoretical value for the study of microgrid optimal dispatching theory. Theoptimization of equipment combination of microgrid is an important reference standard in the early stage ofconstruction. Due to the rapid development of electric vehicles and _the concentration of people using electric vehicles,the charging time will alao be very concentrated. Therefore, it is necessary to consider the impact on the grid causedby the concentrated time charging of electric vehicles when constructing the microgrid. In this regard, the thesisuses Monte Carlo thinking幻build the corresponding model and gives cha屯ing recommendations. | |||||||
