Abstract:In this paper, it is stated that renewable energypower consumption is the prominent problem which China powersystem confronts about green operation.It is analyzed and pointedout that demand response dispatch is a strategic option and effectiveway to improve green operation of Chinese power system.A series ofspecific recommendations are proposed on how to advance demandresponse dispatch in China.

Abstract:In this paper, the variation rule of the air.condi.tioning load in summer regional power grid can be obtained usingstatistical analysis.By overall considering the influencing factors ofair.conditioning load, the forecasting model of summer air.condition.ing load in regional power grid was built.The model was based onthe load curves of the regional power grid, and realized the effectiveseparation of the air.conditioning load curve.Then the Pearson cor.relation coefficient was used to investigate the correlation betweenvarious factors and daily maximum air.conditioning cooling load.Through comparing the correlation coefficient between the dailymaximum air .conditioning cooling load and all kinds of indexes, aneconomic .meteorological comprehensive index, reflecting the factthat the daily maximum air.conditioning load is greatly affected bythe meteorological and socio.economic in a region, was constructed.And the regression analysis was used to extract the change rule ofthe air conditioning cooling load and the comprehensive index.Fi.nally, the accurate prediction of summer air.conditioning load is re.alized.A regional data of power load and its related factors from2006 to 2015 was used as training sample to forecast the summer air.conditioning load in 2016 of the region.The forecasting resultsproved the validity of the proposed model.

Abstract:For the poor operation reliability and low econom.ic benefit of large.scale wind.solar.storage generation system, thispaper adopts multi.objective gravitational search algorithm(GSA) to optimize capacity allocation of wind.solar.storage generation unit.Power output models of generation unit are established, includingwind turbine model, photovoltaic generator model and storage bat.tery model.Wind speed, irradiation and temperature data of an areafrom January to December in 2015 are used to calculate power out.put of wind turbine and photovoltaic cell.The optimal wind.solar.storage system configuration is obtained with capacity of wind tur.bine, photovoltaic cell and battery as decision variables and mini.mum of cost, loss of power supply probability and energy wastagerate as optimal objective.

Abstract:In order to improve the situation of voltage viola.tion in distribution network with high penetration distributed photo.voltaic(PV)system, it is possible to fully utilize the reactive powerregulation ability of grid.connected PV inverter.This paper proposestwo kinds of strategies on distributed PV generation output regula.tion for node voltage violation of medium.low voltage level distribu.tion network.For the first method, each PV node’s voltage sensitivi.ty to its injected reactive power and active power is obtained usingdisturbance.observation method.The available reactive power out.put of the most effective PV access node is calculated and when itsreactive power is not sufficient, its active power is able to regulate.For the second method, aiming at both regulating voltage violationand minimizing the grid active power loss, the reactive power and ac.tive power of all the PV generation systems are optimized from theperspective of global optimization.Through the simulation of IEEE33 nodes distribution network under two typical kinds of operationscenarios, in comparison with the voltage reactive power active pow.er PV output mode, the validity of both methods are proved.

Abstract:Under the background of national air .pollutioncontrol, aiming at the cold area that can not use heat pump or watersource heat pump of buried pipe and low energy efficiency ratio andhigher failure rate of the use of air source heat pump,the energy stor.age heat pump system interconnection clean heating scheme is putforward, which break through the objective limit of single the use oftechnology through the comprehensive technical innovation, in orderto create" no well, no water heat pump system of buried tube".Theconventional air source heat pump utility boundary is expanded andthe stability is enhanced.The investmentis failure rate are reduced,which can provide stability in the transformation of the radiator heat.ing system in hot water 60 degrees.Taking the heating house recon.struction project of the family building in Lanzhou West substationas an example, the scheme design, equipment selection and opera.tion effect analysis are carried out, and the reliability and economyof the heat pump system are verified.

Abstract:With the increasingly serious environmental pollu.tion and energy shortage, the development of clean power energy isincreasing all over the world in recent years, especially the rapid de.velopment of wind power, photovoltaic power and hydropower.Thispaper mainly summarizes and analyses wind power, solar power andhydro power generation from two aspects of technology characteris.tics of clean energy generation and world market development status.

Abstract:Large scale power.grid load friendly interactive sys.tem acts as a mode of protection to secure the running of global pow.er internet while the grid load interactive facilities installed in largeindustrial firms serves as the key action component.This paper intro.duces how to securely install and connect the grid load interactive fa.cilities at load terminals, accomplishing the interactions of produc.tion.load with the end.users and how to disconnect individual’s grid load instantly under power grid emergency situations.

Abstract:Through the distribution transformer operation da.ta, equipment data, the situation of consumer expanding that powersupply company masters, the maximum low.voltage range is judged,which helps the company determine the possible areas of low.volt.age happening and analyze the reasons of three.phase imbalance byimbalanced loads.This paper provides the calculation method ofequivalent current unbalance degree before installing.By the chang.es of current imbalance value and low.voltage consumers’range,the junctions is determined whether is reasonable to avoid the occur.rence of low.voltage because of the human factors before junction.

Abstract:The power supply business hall integrated manage.ment is the demand for electric power marketing management inno.vation, to carry out the comprehensive management of the power sup.ply business hall, to regulate electricity execution of business rulesand standards, to improve work quality and management, service lev.el, to improve the power of the company's economic benefit and so.cial benefit.This paper introduces the management status of powersupply company's business hall, analyzes the demand of the compre.hensive management system of power supply business hall, and putsforward the system design scheme and application prospect.
