多能互补分布式能源系统

多能互补分布式能源系统是传统分布式能源应用的拓展,是一体化整合理念在能源系统工程领域的具象化,使得分布式能源的应用由点扩展到面,由局部走向系统。具体而言,多能互补分布式能源系统是指可包容多种能源资源输入,并具有多种产出功能和输运形式的"区域能源互联网"系统。它不是多种能源的简单叠加,而要在系统高度上按照不同能源品味的高低进行综合互补利用,并统筹安排好各种能量之间的配合关系与转换使用,以取得最合理能源利用效果与效益。

Pluripotent complementary distributed energy system is the extension of the traditional distributed energy application. It is the actual appearance of integration concept in the field of energy systems engineering industry, which makes the distributed energy applications extend from the point to the surface. To be explained, Pluripotent complementary distributed energy system means that the entire system includes a variety of energy resources input model, and output with a variety of functions, finally created "Regional Energy Internet" system. It is not a simple sum of various energy sources, it depends on different system function to make a high efficient complementary utilization and co-ordinate the various arrangements with the relationship between energy use and conversion, the final purpose is to obtain the most rational use of energy effects and benefits. 

多能互补分布式能源系统主要通过多种能源的相互补充、相互协调,提供建筑物冷热负荷和电力供应。分布式能源系统按照“以热定电、并网不上网”的原则,实现电力自给自足,满足能源中心一次能源需求。

多能互补分布式能源有两种模式:一是面向终端用户电、热、冷、气等多种用能需求,因地制宜、统筹开发、互补利用传统能源和新能源,通过天然气热电冷三联供、分布式可再生能源和能源智能微网等方式,实现多能协同供应和能源综合梯级利用;二是利用大型综合能源基地风能、太阳能、水能、煤炭、天然气等资源组合优势,推进风光水火储多能互补系统建设运行。 

分布式能源系统

“分布式能源”(distributed energy resources)是指分布在用户端的能源综合利用系统。一次能源以气体燃料为主,可再生能源为辅,利用一切可以利用的资源;二次能源以分布在用户端的热电冷(值)联产为主,其他中央能源供应系统为辅,实现以直接满足用户多种需求的能源梯级利用,并通过中央能源供应系统提供支持和补充。分布式能源依赖于最先进的信息技术,采用智能化监控、网络化群控和远程遥控技术,实现用户侧能源自动调配、峰值管理、自动计量、现场无人值守等功能。

 

ENERGY DISTRIBUTION SYSTEM

The “distributed energy resources” indicates energy integrated utilization system which spread over the user side. The primary energy resource is gas fuel, and the renewable energy as its complementary energy. The secondary energy sources mainly depending on user side’s heating, electricity and cooling production, and other energy supply system as its subsidiary energy resource. As the result, this system will satisfy the user’s various energy requirement and achieve the goal of energy gradient utilization. 
 
分布式能源综合应用技术优势
遵循“以热定电”“并网不上网”的原则,系统以冷热电三联供系统提供发电、制冷、制热和生活热水为主,发电机组所发电力全部用于本系统循环水泵、水源热泵机组、以及其他动力和照明用电。综合应用技术充分发挥各个子系统的综合优势,以太阳能和水源热泵作为空调系统的补充冷热源,能源的梯级和多机种、多能源的复合应用,提高能源利用率,从而实现节能减排的目标。
 
DISTRIBUTION ENERGY INTEGRATION APPLICATION TECHNOLOGY ADVANTAGE
Follows the principle of “electricity determined by the thermal” and “the power connected to the gird but not a part of grid”, the entire system combined cooling, heating and electricity generating units which will offer the air conditioning and hot water. The generated electricity will be used to the system’s circulating water pump, water source heat pump system and other system, for example lights. The subsystems of this integrated system have reached the best performance by using the solar and water source heat pump as the complementary heat resources, which extremely improved the energy utilization efficiency. As the result, the goal of energy conservation and emission reduction has been achieved.

区域集中供冷供热能源中心像城市给水、电力一样是一项公用事业,是城市的基础设施之一,是为了满足某一特定区域内建筑群落的集中供冷、供热需求,由专门的能源中心集中制造冷水、热水等,通过区域管网进行供给的一个或多个大规模生活热水、中央空调冷热源系统。区域集中供冷供热能源中心采用如分布式能源、地表水水源热泵、污水源热泵、土壤源热泵、光热空调系统等清洁能源技术进行联合和单独使用,具有峰值可调、提高能源系统的多级利用效率、以及提高能源系统的管理效率和减少装机负荷等特点。区域集中供冷供热站目标客户一般为城市综合体、城市高级集中商务区、高等院校等。
 
2、清洁能源供暖系统
该系统主要集中在北方以及南方气候寒冷具有清洁能源资源条件且有区域集中供暖需求的城市。如北京、河北、天津、贵阳等城市,冬季采用燃煤供暖,雾霾天气持续高发、地下水位下降、城市居民供暖需求量较大等特点的城市。采用分布式能源综合应用技术,可减少污染物排放、提高能源利用率、实现节能减排的目标。
 
 
SCOPE OF APPLICATION
REGIONAL CENTRALIZED COOLING AND HEATING ENERGY CENTER
Regional centralized cooling and heating energy center similar to urban water supply, and electricity power supply, it is a utility that is one of the city's infrastructure, to satisfy a particular area of community’s demand of cooling and heating. It is an central air conditioning systems that provides cooling water, hot water etc., through regional network, to one or more of the mass living area.
Regional centralized cooling and heating energy center adopts distributed energy, surface water source heat pump, the sewage-source heat pump, soil source heat pump, air conditioning system and other clean energy technologies for combine and solo use with adjustable peak, improve the utilization efficiency of multi-stage of energy system, and improve the management efficiency and reduce the capacity of energy system load, etc. Regional concentration and cooling computer target customers generally for senior urban context, urban centralized business district, institutions of higher learning, etc.The target customers are urban complex, City advanced centralized business district, and Institutions of higher learning.
 
CLEAN ENERGY HEATING SYSTEM
The system mainly concentrated in the northern and southern of China where the climate is very cold, and has clean energy resource conditions and regional urban central heating demand. Such as Beijing, Heibei, Tianjin and Guiyang, where the cities in Winter need burn coal for heating, has  haze repeatedly happen, underground water fallen, supply of the urban citizen increasing. Use this technology could reduce the emission, increase the utilization of the energy, achieve the goal of energy conservation and emissions reduction.
