Estimating appropriate margins of electric power demands for the developing communities is one of the main issues in the infrastructure design of the urban planning 中文摘要对社区发展而言，估测电力需求量为都市计划中基础设施设计的主要课题之一，而负载预测与电力需求之准确性紧密相关。
It is therefore necessary to have a backup power supply such as the electricity grid to meet the demand when the electricity generated by the renewable energy system is unable to provide the power required 当可再生能源未能提供足够电力，则须要由后备电源（例如市电）补充，以应付电力需求。
America ' s south - western deserts are an abundant source of sunshine that could meet the country ' s power needs several times over without releasing a molecule of carbon dioxide 真正的原因在于，美国西南的沙漠地区有取之不竭的阳光，足可提供全国电力需求总量的几倍，而且不会散发一个二氧化碳的分子。
With rapid growth of the power demand and the in - depth reform of power - station construction management , changes also took place in the industry environment of the investigation and design sector 随着电力需求的高速增长和电力建设体制改革的不断深入，水利水电工程勘察设计企业的环境发生了较大变化。
Users can choose the numbers of gearwheels they want and determine the size of their wind turbines according to their energy needs and the space they have on their balconies or rooftops 只要将滚轮组装，便可产生较大的电力。使用者可以因应他们的电力需求及露台或天台的空间，决定微型风力发电机的大小。
Consequently , it is worth discussing these problems that how to promote price leverage applied in dsm to bring the function of the price in demand regulation into full play in china 如何有效地推进电价在我国电力需求侧管理中的应用,更好地发挥价格杠杆在调节电力需求中的作用,是一个值得深入探讨的课题。
Priority control priority control is the process by which the total loads on the bus is limited to the most critical loads in the system until adequate generation capacity is available to serve all loads 优先级控制优先级控制是指当总负载电力需求大于发电机组的输出时，首先要满足最关键负载的电力需求。
In the end , the decision - making order of scrolling development of cascade hydropower stations is obtained under different power demands by comprehensive analysis 然后运用多种方法进行分析，运用电力电量平衡方法论证开发方案的适应性，通过综合分析得到了不同电力需求下的梯级水电滚动开发决策顺序或者可接受的编序。
We also encourage electricity consumers to even out the demand over different hours of a day to optimise the efficiency of electricity generation , transmission and distribution facilities 此外，我们亦鼓励电力用户调节每日不同时段的用电量，使电力需求的分布较为平均，以便发电、输电和配电设施得以发挥最佳效能。
The growth of electric power consumption has resulted in a corresponding development of power system , in addition , the requirement for the stability of the large system has increased 随着人们生产生活对电力需求的日益增加，电力系统的规模逐步扩大，与此同时，对远距离、大容量的系统的运行稳定性的要求也相应提高。
