"十三五"末,浙江省外购电的总量约占负荷总量的40%,其中特高压交、直流输电容量约为30%。若特高压电力不参与电网调峰,2020年浙江电网最大调峰缺口将超过4 800 MW,调峰形势十分严峻。为此,以调峰充裕度为评价指标,研究了特高压交、直流单一电力参与调峰和联合参与调峰的必要性,并提出特高压电力调峰建议。
The imported electricity accounts for about 40%of the total electrical load of Zhejiang Province by the end of the Thirteenth Five-year Plan, and the UHV AC and DC transmission capacity accounts for about 30%. The maximum gap of peaking shaving will be over 4 800 MW in 2020 , if the UHV AC and DC power does not participate in peak load shaving of Zhejiang power system , and the situation of peak shaving would be serious. In this paper, the necessity of the UHV power single-participating and combined-participating in peak load shaving is investigated by using peak shaving abundance as the evaluation index. Suggestions on peak shaving of UHV electric power are put forward.

在大电网平台下，如何利用受端电网间负荷差异与多电源发电特性来消纳区外水电及缓解受端电网的调峰压力，是中国大规模跨区直流水电输送的关键问题之一。文中以华东电网为背景，从实际应用需求出发，提出了按需供给、多电源互补的大规模跨区特高压直流水电网省两级协调电力控制和电量控制优化调度模型。华东电网2013年典型日模拟调度结果表明，与目前采用的经验调度方法相比，电力控制与电量控制模型下华东电网各省(市)电网负荷平均调峰率分别提高了21.3%和39.3%，调峰效果非常显著；此外，对华东电网2013年全年采用电力控制模型进行日96点试调度运行，结果表明全年平均调峰率提高了20.5%，充分显示了优化水电输送与分配方式的巨大潜力。
Under the large-scale power grid platform, one of the key issues of large-scale trans-regional hydropower transmission via ultra-high voltage direct current(UHVDC)is how to fully utilize the load differences of receiving power grids and the generation characteristics of multiple power sources to accommodate external hydropower and mitigate pressures on peak shaving load.Against the background of East China power grid (ECPG) and proceeding from demand on practical application,this paper proposes two coordinated and optimized dispatching models (the power-control model and the energy-control model) for large-scale trans-regional hydropower transmission via UHVDC in regional and provincial power grids.In the two dispatching models,power is supplied according to demand with the multiple power sources supplementing each other. The simulation scheduling results from ECPG on a typical day in 2013 show that,compared with the present empirical scheduling,the average peak shaving ratio

Based on the analytical investigation on distribution of energy resources,energy production and consump-tion in Guangxi, studies show that utilization of Yunnan hydropower energy is favorable for maintaining energy re-sources security,reducing pressure on energy conservation and emission reduction and power tariff in Guangxi. This paper also studies on the Yunnan to Guangxi power transmission curve in different proportions of power transmission in wet and dry season, and the results show that the smaller the power transmission proportion in dry season is, the lower the installation substitution rate is,the larger the power grid peak regulation pressure is;and the higher the peak regulation strength in thermal power is,the larger the abandoning energy is. When the power transmission ratio is not less than 28%in dry season,the power transmission curve can meet the requirements of power and energy bal-ance and peak regulation in Guangxi Power Grid.

According to the industry characteristics of the service-oriented city and its corresponding power load characteristics, the necessity of accelerating construction of efficiency power plant (EPP) is discussed. The EPP mentioned here can shift electricity usage from peak hours to off-peak hours using thermal storage technology. This paper presents an integrated resource planning (IRP) model with the aim to minimize the total cost over a planning horizon. The EPP at demand side is considered along with traditional supply resources to meet the planning. In addition to common aspects of scheduling, this model takes a peaking capacity constrain into account to meet the big peak-valley difference in the city. Then, an improved dual population invasive weed algorithm (IWO) is proposed for solving the model. Case study results show that the proposed model and the improved algorithm are effective, and the IRP model can realize the system total cost minimization, emission reduction and power pea

随着金沙江、雅砻江、澜沧江流域溪洛渡、向家坝、糯扎渡、锦屏等巨型水电站陆续全部竣工和集中并网发电，中国水电输送规模急剧扩大，大规模水电输送直接影响到中国电力资源大范围合理配置，其消纳和对受电端电网的调峰矛盾凸显。然而，由于送端电网水电调节性能弱和消纳能力有限，中国现行的按照电站自身的运行要求或者送端电网的电力盈余安排输送计划的方式，极易出现“直线”或者“反调峰”水电输送计划，加重了受电端电网调峰压力，不利于水电大规模消纳和发挥其优质的调峰作用。如何根据送受端电网负荷特性差异，发挥跨流域梯级水电站群相互补偿作用，利用不同电源特性以最大程度消纳水电和发挥水电的调峰作用，需要研究水电大规模输送的网网协调、网省协调、厂网协调优化调度方法、补偿机制、调峰阀值和协调策略等。上述问题是中国现阶段特高压直流水电大规模输送核心所在，其研究将能够更加合理配置中国电力资源，缓解受电端电网调峰压力，改善长三角洲、珠江三角洲电源结构，减轻这些地区的雾霾压力，切实保障中国电网安全、经济、环保、可靠运行。
With huge hydropower plants, such as Xiluodu, Xiangjiba, Nuozhadu and Jingping located in Jinshajiang River, Yalongjiang River and Lancangjiang River being completed and put into production, hydropower transmission capacity of ultra high voltage direct current (UHVDC) were expanded rapidly in China. Large-scale hydropower transportation have a strong impact on optimizing configuration of electric power resource in nationwide scope, especially absorbing hydropower for sending power grids and shaving peak load for receiving power grids. Because of the limited regulation capacity of hydropower plants, transportation schedules of hydropower are subject to operating requirement of plants itself and extra electricity in sending power grids. The “straight line” and“opposite peak shaving” transportation schedules occur frequently and have aggravated pressure to peak shaving load in receiving power grids. A new challenge for the coordinating operations is how to utilize load peak
