【摘要】:風光儲電站借助儲能技術(shù)實時地進行能量的存儲和釋放,實現(xiàn)間歇性新能源發(fā)電的“可測性、可控性、可調(diào)性”。然而,一方面,由于當前我國棄風限電問題嚴重,風光儲電站也經(jīng)常處于棄風限電狀態(tài),其儲能系統(tǒng)的調(diào)節(jié)能力不能得到有效的發(fā)揮,造成系統(tǒng)資源的浪費;另一方面,我國面臨棄風限電問題的同時,實際運行中還存在由于風電場自身原因出力不足造成輸送通道未能滿載的局面。因此,建立有效的市場機制激勵風光儲電站參與電力市場中,來實現(xiàn)交易雙方的互利共贏和資源的高效利用,是十分必要的。 論文首先針對風光儲電站特性,從結(jié)構(gòu)上分析了風光儲電站的三大系統(tǒng),并從性能上分析了風光儲電站的7種運行模式以及4種控制策略。并基于國家風光儲輸示范工程的實際運行情況,通過分析其特性探究風光儲電站提供電力輔助服務方面的能力。然后在電監(jiān)會華北局指導下,分別針對不限電和限電兩種情況進行交易機制研究。 當不進行限電時,風電場需按要求進行功率預測預報工作,而風電場時常由于功率預測準確率不達標而受到考核。本文基于風光儲電站的優(yōu)勢和風電場出力的特性,提出了風光儲電站跟蹤發(fā)電曲線能力的有償服務機制,以達到提高風電場風功率預測準確率的目的。并在出力補償服務機制基礎上,建立了出力補償動作的控制策略模型,以實現(xiàn)風光儲電站有限出力調(diào)控能力的高效利用。通過算例驗證,交易機制能實現(xiàn)交易雙方互利共贏的同時減小風電出力波動性對電網(wǎng)的影響。 當進行限電時,風電場需按調(diào)度機構(gòu)下達的發(fā)電計劃進行發(fā)電,而風電場會因自身原因出力不足造成輸送通道未能滿載。本文將風功率預測的指導作用和市場機制的激勵作用引入到通道資源配置中,設計了基于日前風功率預測的發(fā)電裕度交易機制,以實現(xiàn)風電傳輸通道高效運行;并從交易雙方的角度,建立了發(fā)電裕度買賣雙方的交易策略模型,以謀求交易雙方的共贏。通過算例分析,證實交易可以給交易雙方帶來更多的收益;同時在有限的通道資源下輸送更多的風電,實現(xiàn)通道輸出效率的提高。
[Abstract]:The solar power station can store and release energy in real time by means of energy storage technology to realize the "testability, controllability and tunability" of intermittent new energy generation. However, on the one hand, because of the serious problem of waste wind and limited power in our country at present, wind storage power station is often in the state of abandoned wind and limited power, and its regulating ability of energy storage system can not be effectively brought into play, resulting in the waste of system resources; on the other hand, While China is faced with the problem of abandoning wind and limiting electricity, there is a situation that the conveying channel is not fully loaded due to the insufficient output of wind farm itself in actual operation. Therefore, it is necessary to set up an effective market mechanism to encourage the wind storage power station to participate in the electricity market, to realize the mutual benefit and win-win and the efficient utilization of resources. Firstly, according to the characteristics of the wind storage power station, the paper analyzes the three systems of the wind storage power station from the structure, and analyzes the seven operation modes and four control strategies of the wind storage power station from the performance point of view. Based on the actual operation of the National Scenic Storage and Transportation demonstration Project, this paper analyzes the characteristics of the National Scenic Storage Power Station to explore the ability of providing auxiliary power services. Then under the guidance of the North China Bureau of the ECC, the trading mechanism of non-power limit and power-limited is studied respectively. When the power is not limited, the wind farm needs to forecast the power according to the requirement, and the wind farm is often evaluated because the accuracy of power prediction is not up to the standard. Based on the advantages of wind power storage power station and the characteristics of wind farm, this paper presents a paid service mechanism for wind power storage power station to track generation curve, so as to improve the accuracy of wind power prediction in wind farm. On the basis of the force compensation service mechanism, the control strategy model of the force compensation action is established to realize the efficient utilization of the limited output control ability of the wind-energy storage power station. The example shows that the trading mechanism can achieve mutual benefit and win-win while reducing the impact of wind power generation volatility on the power grid. When the power is limited, the wind farm needs to generate electricity according to the power generation plan issued by the dispatching agency, and the wind farm will be unable to fully load the transmission channel due to its insufficient capacity. In this paper, the guiding role of wind power prediction and the incentive effect of market mechanism are introduced into the allocation of channel resources, and a generating margin trading mechanism based on pre-day wind power prediction is designed to realize the efficient operation of wind power transmission channel. From the point of view of both parties, the trading strategy model of generating margin buyer and seller is established in order to seek the win-win situation of both parties. Through the analysis of an example, it is proved that the transaction can bring more benefits to both sides of the transaction, and at the same time, the channel output efficiency can be improved by transmitting more wind power under the limited channel resources.
