【摘要】：智能微電網(wǎng)可以接入多種分布式發(fā)電和儲能單元,尤其是對可再生能源的有效利用,不僅可以為偏遠地區(qū)提供穩(wěn)定電能,而且并網(wǎng)運行時能起到"削峰填谷"的作用,提高公共電網(wǎng)穩(wěn)定性,對解決化石燃料資源短缺問題和環(huán)境污染問題有重大意義。微電網(wǎng)中分布式發(fā)電及儲能單元容量配置關系到微網(wǎng)整個生命周期經(jīng)濟性和供電可靠性,是微網(wǎng)規(guī)劃設計階段的重要工作。結(jié)合當前節(jié)能減排要求,研究碳稅機制對微網(wǎng)配置的影響,可以為微網(wǎng)的低碳化配置提供參考。本文針對三種典型的微網(wǎng)結(jié)構(gòu),在碳稅機制下考慮不同碳稅稅率,研究微電網(wǎng)中各類分布式發(fā)電和儲能單元容量配置問題,做了如下研究工作:首先給出了光伏系統(tǒng)、風力發(fā)電機、微型燃氣輪機輸出功率模型和蓄電池的充放電功率與荷電狀態(tài)關系模型,為后文計算不同工況下各類電源輸出功率奠定基礎。然后針對單節(jié)點獨立微電網(wǎng)、單節(jié)點并網(wǎng)微電網(wǎng)和多節(jié)點獨立微電網(wǎng)這三類微網(wǎng)的結(jié)構(gòu)和運行特征,以優(yōu)先利用可再生能源為主,分別制定了三類微網(wǎng)的運行策略,并依此給出了各類微網(wǎng)中負荷缺電率、可再生能源滲透率和可再生能源利用率計算方法。在此基礎上,考慮不同碳稅稅率的影響,以微網(wǎng)生命周期經(jīng)濟性最優(yōu)為優(yōu)化目標,結(jié)合約束條件,構(gòu)建三類微網(wǎng)的優(yōu)化配置模型。在多節(jié)點獨立微網(wǎng)中,還考慮了節(jié)點間功率交互產(chǎn)生的線路損耗。最后通過算例仿真得到三類典型結(jié)構(gòu)微網(wǎng)在不同碳稅稅率下的電源優(yōu)化配置方案,分析了碳稅稅率對微網(wǎng)中各類電源配置容量、可再生能源滲透率、碳排放和微網(wǎng)經(jīng)濟性的影響,并進一步從三類微網(wǎng)結(jié)構(gòu)和運行策略角度,分析了碳稅機制產(chǎn)生的不同影響,從而在考慮不同碳稅稅率的情況下,為智能微電網(wǎng)電源優(yōu)化配置提供了參考。
[Abstract]:Smart micro grid can access a variety of distributed generation and energy storage unit, especially the effective utilization of renewable energy, not only can provide stable power to remote areas, and the grid operation can play a "peak" effect, improve the public power grid stability, is of great significance to solve the problem of shortage of fossil fuel resources and the problem of environmental pollution. The micro grid distributed generation and energy storage capacity allocation unit related to microgrid throughout the life cycle of the economy and reliability of power supply, is an important work of micro network planning and design stage. Combined with the current energy-saving emission reduction requirements, the research on effect of carbon tax on the micro mechanism of network configuration, can provide a reference for low carbon micro configuration net. This paper focuses on three kinds of typical microgrid structure, considering the different carbon tax on carbon tax mechanism, research on various types of distributed generation and micro grid energy storage unit capacity allocation problem, do The research work is as follows: firstly, photovoltaic system, wind power generator, charge and discharge power of micro gas turbine power output model and battery state of charge and the relational model, under different conditions of various types of power supply output power which lays the foundation for later calculation. Then the single point independent micro grid, single node and multi node grid microgrid these three types of independent micro grid structure and operation of microgrid characteristics, to give priority to the use of renewable energy, were developed three kinds of micro grid operation strategy, and puts forward the load rate of all kinds of micro power network, renewable energy and renewable energy by the calculation method of permeability rate. On this basis, considering the influence of different carbon tax, the micro network life cycle economy as the optimization goal, combined with the constraints, the paper constructs three types of optimal allocation model of microgrid. In a multi node independent micro grid, are also considered The line loss between the nodes of interactive power generated. Finally through the simulation example of three typical power structure optimization scheme of microgrid in different carbon tax under the analysis of the carbon tax on all types of power distribution capacity in the micro grid, renewable energy penetration, the influence of carbon emissions and micro network economy, and further from the three types of micro grid structure and operation strategy angle, analyzed the different influence mechanism of carbon tax, and in consideration of different carbon tax case, provide a reference for the smart micro grid power optimization configuration.
