| dc.description.abstract | In recent years, due to the rapid development of industry and commerce in various countries, as well as the progress of science and technology and the increase of population. The start of mass production of energy and the acceleration of the consumption of basic energy sources has also led to the depletion of fossil fuels and the emission of greenhouse gases from energy production. An increase of 1.5°C would lead to extreme climates such as coral bleaching, sea level rise, droughts and storms, and the increasing displacement of many families. Over the next decade, we must reduce carbon dioxide emissions by 7.6% per year in order to have the chance of slowing the pace of global warming, moderating dramatic changes in the climate and curbing continued warming. Therefore, we must face up to the problem of global warming and implement the commitment and responsibility of energy conservation and carbon reduction. This also makes the traditional fossil fuel power generation gradually replaced by clean renewable energy, which will reduce the greenhouse effect and pollution caused by the traditional fossil fuel power generation. Countries also began to set clear development goals for clean energy, and actively and continuously encouraged the promotion of renewable energy policies and measures, making the importance of renewable energy more and more attention.
The purpose of this study is to take the users of Taiwan high voltage power industry as the research object on the basis of three-stage time of use, and take the lowest total electricity cost as the target. A mathematical model is established to plan the optimal configuration of solar power generation combined with energy storage system by means of mathematical programming. In addition to the large power consumption provisions issued by the government, the policy of 10% of renewable energy generation equipment must be set, which means that the industry will start to move towards renewable energy generation as the target. If renewable energy power can be incorporated into the time of use power system, it can assist or slow down the power supply provided by Taiwan Electric Power Company. Therefore, if solar power is used for industrial energy users, the energy management mode will need to be further discussed. The optimal energy storage and release strategy of the battery should also be coordinated through the effective utilization of solar energy generation and energy storage equipment and proper planning of power supply capacity. In addition, the optimal solar panel setting area and energy storage system device capacity will be obtained according to the demand of industrial users, and distributed electric energy and energy storage equipment will be brought into the optimal operation mode through real-time regulation. In addition, sensitivity analysis is conducted for different unit setup costs of the energy storage system. The results show that when solar power generation, time price and energy storage system are used together, the power consumption during peak hours can be greatly reduced, and the total power consumption cost can also be significantly reduced by 37%. It can not only reduce the burden of power supply, but also make the benefit of peak load cutting more obvious, and disperse the peak power consumption to change the habit of electricity consumption. | en_US |
