Research On The Collaborative Optimization Of A Regional Energy System In Langfang

Air pollution in Langfang city is more serious in recent years,therefore it is imperative to start governance,but along with the city was incorporated into national ‘forbidden coal area' scope,coal-fired boilers must be all transformed,as most of them are heating boilers in winter.Regular transformation methods are the ‘coal to gas' or ‘coal to electricity',which need to build new power equipment,investment and operation cost is relatively high,and power equipment is idle f or a long time except the heating period,load rate is low.In this background,we imagine and put forward a new reform mode in this article,that is to construct a system of regional energy micro network,release of both high power equipment in the area of redundant capacity to meet the heating requirements.Based on the energy system of a certain area in Langfang city as the research object,we researched four users in this area from the general situation of the power station,the method,territory,time and rules of energy usage.On the basis of detailed investigation and research,this paper is a comprehensive statistics and analysis of all users within the area of each energy system configuration and operation situation,by using the theory of system energy efficiency as well as the knowledge of the related subjects such as economics,marketing,operational research,etc.,which is carried out by the qualitative and quantitative analysis of the energy supply and load rate of the existing power supply equ ipment.In the target area of this research,there is rigid heating energy demand and implicit cooling cost-reduction demand on one hand;and on the other hand,the installed capacity of existing high energy supply equipment is generally large,low operating load rate and high equipment idle rate,although the cost is low,it isn't fully played to the ability of the equipment.So in consideration of this two aspects of the case above,we build a collaborative network of micro supply mode in target area in this paper.We set up a system framework for the heating and cooling condition,which plans and designs the system of heat and cold supply network,control network and the network users,analyzes and measures trading patterns of volume of heat,cold,trading price and trading volume.In order to reflect the value of this micro supply mode in the target area,respectively from the point of view of economy,technology and environmental protection in the quantitative analysis,we evaluate the differences between the original energy systems,conventional energy systems and it.Regional energy system of micro network makes each individual users of energy system become a collaborative and intercoordinate network system,without adding new power equipment,but with the existing efficient high-powered equipment to meet the energy demand of area,in this way we can achieve reduction in investment and satisfy the demand,at the same time we can also reduce energy costs,improve the existing energy supply equipment load rate,save energy and reduce pollution discharge.The research results of this paper can provide some new modes of thinking and theoretical support for the regional energy supplement and the ‘coal to gas' or ‘coal to electricity' project,which plays a certain role in promoting the overall investment of social energy facilities.
