【摘要】：电能作为二次能源也是常用的终端能源,是原始能源到电力消费者的重要过渡。其中,电价关乎电力市场各参与方的利益,也侧面影响着能源和环境的可持续发展。一直以来电力行业作为自然垄断行业,忽略了电力产品的实际价值,引发了一系列问题。智能电网是对传统电网的智能化改革,旨在提高能源的生产和利用效率,其中面向需求响应的电价形成机制是完善智能电网的关键部分。本文首先对智能电网的国内外研究现状进行了综述,其次对基于激励的需求响应策略和基于价格的需求响应策略的研究现状分类综述,再次详细介绍了电力产品定价的原则、依据和发展。然后对需求响应理论和价格需求响应策略进行全面综述,比较不同价格需求响应策略的优缺点与适用性,并引入基于价格负荷弹性的需求响应模型。实证部分建立基于负荷比例的实时电价模型,结合需求响应模型,代入某地区118户居民连续十天每半小时的负荷数据,仿真得出实时电价情况下的负荷和电价,对比需求响应实施前后的用户侧、供电侧和环境侧的成本效益变化,评估需求响应策略的实施效果。结果表明价格需求响应策略对于削峰填谷和减少用电负荷有显著效果,并且能提升社会总收益。
[Abstract]:As a secondary energy, electric energy is also a common terminal energy, which is an important transition from primary energy to power consumers. Among them, electricity price is related to the interests of all participants in the electricity market, and also affects the sustainable development of energy and environment. Power industry as a natural monopoly industry has ignored the actual value of power products and caused a series of problems. Smart grid is an intelligent reform of traditional power grid, which aims to improve the efficiency of energy production and utilization. The mechanism of electricity price formation based on demand response is a key part of the improvement of smart grid. This paper firstly summarizes the domestic and international research status of smart grid, secondly classifies the research status of demand response strategy based on incentive and demand response strategy based on price, and then introduces the principle of power product pricing in detail. Basis and development Then the demand response theory and the price demand response strategy are comprehensively reviewed to compare the advantages and disadvantages of different price demand response strategies and to introduce a demand response model based on price load elasticity. In the empirical part, a real time electricity price model based on load ratio is established. Combining with demand response model, 118 households in a certain area are replaced by the load data per half an hour for 10 consecutive days, and the load and electricity price under the condition of real time electricity price are obtained by simulation. Compare the changes of cost and benefit between user side, power side and environment side before and after the implementation of demand response, and evaluate the implementation effect of demand response strategy. The results show that the price demand response strategy has a significant effect on cutting the peak and filling the valley and reducing the power load, and can increase the total social income.
