【摘要】：由于風(fēng)電功率的波動(dòng)性和不確定性，大規(guī)模風(fēng)電聯(lián)網(wǎng)運(yùn)行給電網(wǎng)安全經(jīng)濟(jì)運(yùn)行帶來(lái)了諸多不利影響，制約了既有電網(wǎng)的風(fēng)電接納規(guī)模。儲(chǔ)能系統(tǒng)具有對(duì)功率和能量的時(shí)空平移能力，可有效抑制風(fēng)電功率的波動(dòng)性提高風(fēng)電功率的確定性，因而被認(rèn)為是提高既有電網(wǎng)風(fēng)電接納規(guī)模的有效手段。然而在目前的技術(shù)水平下，儲(chǔ)能系統(tǒng)造價(jià)依舊較為昂貴。因此，如何選擇儲(chǔ)能系統(tǒng)的運(yùn)行控制目標(biāo)、如何設(shè)計(jì)儲(chǔ)能系統(tǒng)的運(yùn)行控制策略及其經(jīng)濟(jì)性評(píng)價(jià)是大規(guī)模儲(chǔ)能應(yīng)用研究領(lǐng)域的重要課題。 本文針對(duì)風(fēng)電調(diào)度過(guò)程中因過(guò)分高估風(fēng)電功率不確定性風(fēng)險(xiǎn)而導(dǎo)致的棄風(fēng)限電問(wèn)題，提出利用大規(guī)模儲(chǔ)能提高風(fēng)電功率的確定性，防止電網(wǎng)過(guò)度預(yù)留寶貴空間，提高風(fēng)電的調(diào)度入網(wǎng)規(guī)模。提出了基于概率區(qū)間預(yù)測(cè)的風(fēng)電滾動(dòng)調(diào)度策略；研究了應(yīng)對(duì)風(fēng)電調(diào)度風(fēng)險(xiǎn)的儲(chǔ)能系統(tǒng)運(yùn)行控制策略；構(gòu)建了儲(chǔ)能系統(tǒng)經(jīng)濟(jì)性評(píng)估模型，分不同的概率區(qū)間預(yù)測(cè)場(chǎng)景評(píng)估了其經(jīng)濟(jì)性。研究工作能夠?yàn)槔么笠?guī)模儲(chǔ)能提高風(fēng)電接納規(guī)模研究提供參考，具有一定的工程實(shí)踐意義。
[Abstract]:Due to the fluctuation and uncertainty of wind power, large-scale wind power network operation has brought many adverse effects to the safe and economic operation of power grid, and restricted the scale of wind power acceptance of the existing power grid. The energy storage system has the ability of time and space translation of power and energy, which can effectively restrain the fluctuation of wind power and improve the certainty of wind power. Therefore, it is considered to be an effective means to increase the scale of wind power acceptance in existing power grids. However, under the present technical level, the cost of energy storage system is still more expensive. Therefore, how to select the operation control target of energy storage system, how to design the operation control strategy of energy storage system and its economic evaluation are important topics in the field of large-scale energy storage application research. In view of the problem of abandoning wind power limit caused by overestimating the uncertainty risk of wind power in wind power dispatching process, this paper proposes to use large-scale energy storage to improve the certainty of wind power, and to prevent excessive reserve of valuable space in power grid. Increase the scale of wind power dispatching network. The rolling scheduling strategy of wind power based on probabilistic interval prediction is put forward, the operation control strategy of energy storage system is studied to deal with the risk of wind power dispatching, and the economic evaluation model of energy storage system is constructed. Different probabilistic interval prediction scenarios are used to evaluate its economy. The research work can provide a reference for the study of using large scale energy storage to increase the scale of wind power acceptance, and has a certain engineering practical significance.
