【摘要】：我国目前空气污染严重,为了满足绿色环保、节能减排的需求,也为了改善我国的能源供给结构,在未来几年,可再生分布式能源仍会保持较高增速。微电网是一个可以有效整合可再生分布式电源、储能、负荷等设备的电力系统,可以做到大量消纳分布式能源出力的作用,促进新能源的发展。同时,我国新电改正在进行,售电侧放开意味着微电网作为5类售电主体可以参与电力市场的交易。根据世界电力市场的经验,微电网参与电力市场可以创造经济价值也可以帮助主网"削峰平谷",而能效管理是其中的关键一环。研究生期间参与863计划(2014AA052001),在此项目中对微电网用户侧能效管理优化进行了研究。本文首先介绍了微电网能效管理的发展情况和涉及微电网能效管理的几个关键技术。从能效管理的基础分布式电源出力预测和负荷预测入手,分析并比较了不同预测手段的优缺点,最终选择了更符合微电网特点的基于统计学的小波神经网络作为预测模型。然后基于电力市场机制选择了日前调度和实时调度相结合的调度策略,在不同时间尺度下对微电网进行优化,这有效解决了日前预测误差带来的影响,提升了经济效益。接着,文章根据微电网的特点建立了数学模型,并结合微电网的实际数据在Matlab平台上进行仿真验证。然后,为了实现能效管理的自动化和智能化要求,基于Qt平台实现了能效管理的软件设计,可以在软件中实现预测、调度、监控等功能,便于微电网的运营管理。
[Abstract]:China's current air pollution is serious, in order to meet the green environmental protection, energy-saving emission reduction requirements, in order to improve the structure of energy supply in our country, in the next few years, renewable distributed energy will continue to maintain a high growth rate. The micro grid is an effective integration of renewable distributed power, energy storage, power system load and other equipment. You can do a lot of consumptive distributed energy generation effect, promote the development of new energy. At the same time, China's new electricity reform is underway, the sale of electricity side release means that micro grid as the 5 kind of the sale of electricity in the electricity market can be subject to power. According to the world market experience, micro grid in power market can create economic value can also help the main peak of Pinggu ", and the energy management is the key part. Graduate students participated in 863 plan (2014AA052001), in the project of micro grid user side energy management optimization Were studied. This paper first introduces the development of micro grid energy management and micro grid energy management involves several key technologies. Starting from the basic energy management of distributed power output prediction and load prediction, analyzed and compared the advantages and disadvantages of different forecasting methods, the final choice was more in line with the characteristics of micro grid and wavelet neural network based on the statistics as a forecasting model. Then the power market mechanism based on the day before the selection of scheduling and real-time scheduling combining scheduling strategy in different time scales to optimize the micro grid, which effectively solved the impact on the former prediction error, improve the economic efficiency. Then, the paper establishes the mathematical model according to the characteristics of micro the grid, combined with the actual data of the micro grid simulation on the Matlab platform. Then, in order to realize the automation and intelligent energy management requirements, Based on the Qt platform, the software design of energy efficiency management is realized. It can realize the function of forecasting, scheduling, monitoring and so on in the software, so as to facilitate the operation and management of the microgrid.
