【摘要】：大力發(fā)展新能源是推進(jìn)我國(guó)能源改革,實(shí)現(xiàn)能源結(jié)構(gòu)轉(zhuǎn)變的當(dāng)務(wù)之急,具有重要的戰(zhàn)略意義。我國(guó)新能源資源總量巨大,分布相對(duì)集中、與負(fù)荷中心呈逆向分布的特點(diǎn),因此開發(fā)主要采用“規(guī)�；_發(fā)、集中并網(wǎng)”的模式。但是受能源技術(shù)、源網(wǎng)建設(shè)等影響,新能源在裝機(jī)容量大幅上升的同時(shí),新能源利用率卻持續(xù)下降,新能源的消納問題成為了短時(shí)的瓶頸,很大程度上限制了我國(guó)新能源的進(jìn)一步發(fā)展。為滿足電力系統(tǒng)運(yùn)行模擬對(duì)新能源出力數(shù)據(jù)的精準(zhǔn)需求,為含大規(guī)模新能源電力系統(tǒng)運(yùn)行模擬提供基礎(chǔ),本文首先開展了面向電力系統(tǒng)規(guī)劃及運(yùn)行模擬建模的風(fēng)電出力特性分析以及出力重構(gòu)研究。從時(shí)間效應(yīng)和空間效應(yīng)兩個(gè)角度分析了風(fēng)電出力的隨機(jī)波動(dòng)特性,對(duì)風(fēng)電出力特性進(jìn)行定量評(píng)價(jià)分析,研究了風(fēng)電出力特性評(píng)價(jià)分析指標(biāo)體系;針對(duì)現(xiàn)有研究中利用經(jīng)驗(yàn)分布模擬風(fēng)電出力的缺陷,從多時(shí)間尺度上對(duì)風(fēng)電場(chǎng)出力進(jìn)行重構(gòu),并應(yīng)用實(shí)際風(fēng)電場(chǎng)數(shù)據(jù)驗(yàn)證重構(gòu)算法的有效性。風(fēng)力發(fā)電和光伏發(fā)電為代表的新能源發(fā)電相比于傳統(tǒng)電源表現(xiàn)出明顯的出力隨機(jī)性和不確定性,開展電力系統(tǒng)規(guī)劃設(shè)計(jì)工作需要充分計(jì)及新能源發(fā)電的特點(diǎn),建立合理的新能源發(fā)電出力模擬模型以及考慮新能源的電力系統(tǒng)運(yùn)行模擬模型。為滿足考慮大規(guī)模新能源接入的電力系統(tǒng)規(guī)劃工作需求,本文研究了考慮大規(guī)模新能源接入的電力系統(tǒng)運(yùn)行模擬優(yōu)化建模。計(jì)及不同的運(yùn)行模擬目標(biāo),提出了新能源出力特征指標(biāo),以及新能源發(fā)電典型出力場(chǎng)景的篩選原則和方法;建立了火電、核電、水電等常規(guī)電源的子模擬模型,并根據(jù)不同的省區(qū)間電力電量交換模式,提出了輸電線路電力電量交換模型以及電力電量交換流程;在此基礎(chǔ)上,考慮系統(tǒng)運(yùn)行多約束條件,計(jì)及多種電源的優(yōu)化協(xié)調(diào),提出了含大規(guī)模新能源電力系統(tǒng)運(yùn)行模擬優(yōu)化模型;進(jìn)一步分別考慮電力系統(tǒng)長(zhǎng)期、短期運(yùn)行約束,將提出的模型和方法應(yīng)用于我國(guó)實(shí)際電網(wǎng)算例系統(tǒng),開展了系統(tǒng)運(yùn)行模擬實(shí)證研究以及新能源消納研究。結(jié)合我國(guó)實(shí)際電網(wǎng)的大規(guī)模新能源消納需求,為指導(dǎo)我國(guó)大規(guī)模新能源基地的實(shí)際消納,本文從風(fēng)光儲(chǔ)聯(lián)合發(fā)電和風(fēng)火打捆聯(lián)合輸電兩方面研究了提高新能源消納能力的電力系統(tǒng)優(yōu)化規(guī)劃方法。通過對(duì)比分析負(fù)荷特性和電源出力特性的差異,研究了影響新能源消納能力的關(guān)鍵因素;在此基礎(chǔ)上,以風(fēng)光儲(chǔ)聯(lián)合系統(tǒng)輸出功率變化率為目標(biāo)函數(shù),有功功率偏差率、峰谷斜率總和、輸出功率波動(dòng)率為約束條件,提出了風(fēng)光儲(chǔ)聯(lián)合系統(tǒng)的容量?jī)?yōu)化配置流程;以風(fēng)電棄風(fēng)率小、系統(tǒng)經(jīng)濟(jì)性好、電力系統(tǒng)安全穩(wěn)定等為原則,提出了風(fēng)火打捆輸電協(xié)調(diào)優(yōu)化規(guī)劃方法,并開展了電力系統(tǒng)優(yōu)化規(guī)劃實(shí)證研究。本文的研究?jī)?nèi)容對(duì)于實(shí)際電網(wǎng)中跨區(qū)域互聯(lián)電力系統(tǒng)的新能源消納研究與電力系統(tǒng)規(guī)劃研究具有重要工程指導(dǎo)意義。
[Abstract]:The development of new energy is to promote China's energy reform, realize the transformation of energy structure a pressing matter of the moment, has important strategic significance. China's total amount of new energy resources is huge, the distribution is relatively concentrated, is the reverse distribution and load center, so the development mainly adopts "the scale of development, integration" mode. But by energy technology effect of source, network construction, new energy in the installed capacity increased sharply at the same time, new energy utilization rate has continued to decline, new energy consumptive problem has become the bottleneck of the short term, largely restricted the further development of China's new energy. In order to meet the precise needs of power system operation simulation output data of new energy provide the basis for the operation, with large-scale new energy power system simulation, this paper carried out for power system planning and operation simulation modeling of wind power output characteristics analysis and output The reconstruction of the random fluctuation of wind power output. The analysis from two angles of time effect and space effect, the output characteristics of wind power in the quantitative evaluation analysis of wind power output characteristics of the evaluation index system for the distribution of defect analysis; simulation of wind power output using the experience of current research of wind power from reconstruction the multi time scale, and the effectiveness of the verification of the actual wind farm data reconstruction algorithm. The wind power generation and photovoltaic power generation as the representative of the new energy power generation compared to the traditional power supply output showed the randomness and uncertainty of power system planning and design work, carry out the need to fully gauge and characteristics of new energy power generation, to establish a reasonable the new energy power generation simulation model and operation simulation model of power system new energy into account. In order to meet the power system with large-scale new energy industry planning for access Demand, the simulated operation optimization modeling of large-scale power systems of new energy access. And considering the different operation simulation target, put forward the new energy output characteristics, and new energy power generation output typical scene selection principles and methods; the thermal power, nuclear power, hydropower and other conventional power sub model, and exchange according to the power of different provinces, the power transmission line switching model and the electric power exchange process; on this basis, considering the system operation constraints, optimization and coordination and a variety of power meter, put forward a simulation optimization model with operation of large-scale new energy power system; further power system considering the long-term, short-term operation the application of constraint, the models and methods proposed in our practical grid calculation system, carry out the system operation simulation empirical research and new energy Consumption research. Combining with the large-scale new energy consumptive demand of China's actual power grid, as the actual consumptive guiding China's large-scale new energy base, the hybrid photovoltaic and wind power generation and wind & thermal transmission combined the two aspects of the improved optimization method of power system planning new energy consumptive ability. Through the comparative analysis of different load characteristics and output characteristics power, key factors to study the influence of the new energy consumptive ability; on this basis, the objective function is the rate of output power of wind solar storage combined system changes, active power deviation rate, peak and valley slope total output power fluctuation rate as the constraint conditions, proposed capacity optimization process scenery storage system combined with wind power; the rate of abandoned wind system, good economy, safety and stability of power system as the principle, proposed wind & thermal transmission coordination optimization planning method, and carry out the optimization of power system An empirical study on planning. This paper has an important guiding significance for the construction of new energy consumptive and research of power system planning of cross regional interconnected power systems in an actual power grid.
