【摘要】：隨著全球能源危機和溫室效應(yīng)的加劇,微網(wǎng)技術(shù)受到越來越多的關(guān)注。微網(wǎng)能量管理和優(yōu)化設(shè)計是微網(wǎng)研究不可或缺的兩大課題,本文以這兩大課題作為核心研究內(nèi)容,主要研究內(nèi)容及所做工作包括以下幾個方面。1)研究了微網(wǎng)中典型分布式電源、儲能單元、典型冷/熱供給設(shè)備等各種元件的準(zhǔn)穩(wěn)態(tài)仿真模型,以及負(fù)荷和可再生資源數(shù)據(jù)的隨機生成方法。2)針對并網(wǎng)的CCHP型微網(wǎng)和獨立型微網(wǎng),本文提出了不同能量管理方法。針對CCHP型微網(wǎng)系統(tǒng),本文提出了以日運行費用最小為優(yōu)化目標(biāo)的優(yōu)化調(diào)度模型,模型以微網(wǎng)系統(tǒng)電、熱、冷功率的平衡和各設(shè)備的運行約束為約束條件,采用混合整數(shù)線性規(guī)劃算法進(jìn)行優(yōu)化計算。針對包含不同設(shè)備的獨立型微網(wǎng),本文提出了不同的協(xié)調(diào)控制策略,策略中允許儲能單元和柴油發(fā)電機分別做主電源,在保證系統(tǒng)穩(wěn)定的情況下,實現(xiàn)可再生能源利用的最大化。3)針對CCHP型微網(wǎng)系統(tǒng),本文建立了基于雙層的微網(wǎng)多目標(biāo)優(yōu)化設(shè)計模型。該多目標(biāo)模型從經(jīng)濟性、環(huán)保性兩方面綜合考慮了微網(wǎng)投資規(guī)劃問題。模型外層用于實現(xiàn)微網(wǎng)系統(tǒng)的容量優(yōu)化,內(nèi)層用于實現(xiàn)微網(wǎng)系統(tǒng)的動態(tài)經(jīng)濟調(diào)度。4)針對獨立型微網(wǎng)系統(tǒng),本文建立了確定性優(yōu)化設(shè)計模型和計及不確定性的隨機機會約束規(guī)劃模型。在兩種優(yōu)化模型中綜合考慮了微網(wǎng)經(jīng)濟性、供電可靠性、環(huán)保性等多種經(jīng)濟技術(shù)指標(biāo)。優(yōu)化過程中,選取設(shè)備類型和裝機容量同時進(jìn)行優(yōu)化設(shè)計。其中,隨機機會約束規(guī)劃模型中,選取供電可靠性作為機會規(guī)劃的約束。
[Abstract]:With the global energy crisis and the aggravation of Greenhouse Effect, more and more attention has been paid to microgrid technology. This paper takes these two topics as the core research content, the main research content and the work includes the following aspects. 1) the typical distributed power generation and energy storage unit in the microgrid are studied. The quasi-steady simulation model of various components such as typical cold / heat supply equipment and the random generation method of load and renewable resource data. 2) for grid-connected CCHP microgrids and independent microgrids. In this paper, different energy management methods are proposed. For CCHP microgrid system, this paper presents an optimal scheduling model with the minimum daily operating cost as the optimization objective. The model is based on the electricity and heat of the microgrid system. The balance of cold power and the operation constraints of each equipment are the constraints, and the mixed integer linear programming algorithm is used to optimize the calculation. Different coordinated control strategies are proposed for the independent microgrids with different equipments. In the strategy, the energy storage unit and diesel generator are allowed to be the main power supply separately. Under the condition of ensuring the stability of the system, the renewable energy utilization can be maximized. 3) for the CCHP microgrid system. In this paper, the multi-objective optimization design model of microgrid based on double-layer is established. The multi-objective model is based on economy. The model outer layer is used to realize the capacity optimization of the microgrid system, and the inner layer is used to realize the dynamic economic scheduling of the microgrid system. 4) for the independent microgrid system. In this paper, the deterministic optimization design model and the stochastic chance constrained programming model with uncertainty are established. In the two optimization models, the economy of microgrid and the reliability of power supply are considered synthetically. Environmental protection and other economic and technical indicators. In the process of optimization, select the type of equipment and installed capacity at the same time to optimize the design. Among them, in the stochastic opportunity constraint programming model. Power supply reliability is chosen as the constraint of opportunity programming.
