【摘要】：全球的能源問(wèn)題越來(lái)越突出,成為限制經(jīng)濟(jì)發(fā)展的一大因素,如何有效利用風(fēng)能、太陽(yáng)能、水能等清潔可再生的能源也越來(lái)越被人們重視。風(fēng)光水互補(bǔ)發(fā)電系統(tǒng)利用三種能源的互補(bǔ)性使系統(tǒng)功率輸出更加穩(wěn)定。另外,儲(chǔ)能系統(tǒng)憑借其可充可放的運(yùn)行特性,能有效克服可再生能源發(fā)電系統(tǒng)的不確定性。 首先,本文提出了風(fēng)光水互補(bǔ)發(fā)電系統(tǒng)的調(diào)度策略,力求對(duì)上述系統(tǒng)的穩(wěn)定、經(jīng)濟(jì)運(yùn)行做出貢獻(xiàn)。在綜合考慮了投資、系統(tǒng)運(yùn)營(yíng)成本、環(huán)境治理等因素,以及孤網(wǎng)、并網(wǎng)兩種運(yùn)行方式的前提下,本文首先建立了最低成本的優(yōu)化模型。在此基礎(chǔ)上,進(jìn)一步提出了風(fēng)光水互補(bǔ)發(fā)電系統(tǒng)的調(diào)度策略,實(shí)現(xiàn)了三種新能源輸出功率的最佳配置。最優(yōu)運(yùn)行和調(diào)度策略可以評(píng)估系統(tǒng)在不同運(yùn)行方式下的經(jīng)濟(jì)性能,提高互補(bǔ)系統(tǒng)的可靠性和靈活性。 再次,本文提出了一種基于場(chǎng)景優(yōu)化的儲(chǔ)能優(yōu)化調(diào)度及安全約束機(jī)組模型。目的在于使能耗最小化,并滿(mǎn)足電網(wǎng)安全約束、做好儲(chǔ)備計(jì)劃以及調(diào)度約束方案。另外,風(fēng)力波動(dòng)的不確定性是通過(guò)蒙特卡洛仿真和拉丁超立方體技術(shù)來(lái)模擬的。之后我們利用一種可計(jì)算的、混合整數(shù)線(xiàn)性規(guī)劃算法來(lái)有效的解決模型問(wèn)題。最后,我們用IEEE3機(jī)6節(jié)點(diǎn)和10機(jī)39節(jié)點(diǎn)系統(tǒng)來(lái)對(duì)這種模型進(jìn)行測(cè)試,其結(jié)果能夠?qū)λ岢龅哪Ｐ驮讷@得優(yōu)化儲(chǔ)能能力、經(jīng)濟(jì)調(diào)度和機(jī)組組合等方面進(jìn)行闡述。 最后,本文新能源互補(bǔ)運(yùn)行和儲(chǔ)能優(yōu)化調(diào)度進(jìn)行了總結(jié)和展望。
[Abstract]:Global energy problems are becoming more and more prominent and become a major factor restricting economic development. How to effectively utilize clean and renewable energy such as wind energy solar energy and water energy has been paid more and more attention. The wind-water complementary power generation system makes the system power output more stable by utilizing the complementarity of three kinds of energy sources. In addition, energy storage system can effectively overcome the uncertainty of renewable energy generation system with its rechargeable and rechargeable operating characteristics. First of all, this paper puts forward the dispatching strategy of the wind-water complementary power generation system, in order to make a contribution to the stability and economic operation of the system mentioned above. On the premise of synthetically considering the factors of investment, system operation cost, environmental treatment, and two operation modes of isolated network and connected network, this paper first establishes the optimization model of the lowest cost. On this basis, the scheduling strategy of the wind-water complementary power generation system is put forward, and the optimal configuration of the output power of three new energy sources is realized. The optimal operation and scheduling strategy can evaluate the economic performance of the system under different operation modes and improve the reliability and flexibility of the complementary system. Thirdly, this paper presents an optimal scheduling and security constrained unit model based on scenario optimization. The purpose of this paper is to minimize energy consumption and meet grid security constraints. In addition, the uncertainty of wind fluctuation is simulated by Monte Carlo simulation and Latin hypercube technology. Then we use a computable mixed integer linear programming algorithm to solve the model problem effectively. Finally, we test this model with IEEE3 6-bus and 10-machine 39-bus systems. The results show that the proposed model can obtain the optimal energy storage capacity, economic scheduling and unit combination. Finally, this paper summarizes and prospects the complementary operation of new energy and optimal scheduling of energy storage.
