Description

A kind of efficiency operation reserve for micro- energy of providing multiple forms of energy to complement each other
Technical field
The invention belongs to Generation Control field, it is related to a kind of efficiency operation reserve for micro- energy of providing multiple forms of energy to complement each other.
Background technology
With deepening constantly that the energy is reformed, by distributed photovoltaic, wind-power electricity generation, miniature gas turbine, biomass power generation, The clean energy resource such as solar energy optical-thermal and energy storage and renewable energy forms by different forms and administrative unit constitute it is miniature Energy net is the developing direction of present energy technology.The light being made up of distributed photovoltaic and energy storage stores up integral system or by wind The honourable storage system of electricity, photovoltaic and energy storage composition solves the problems, such as the local use of wind energy and luminous energy in Demand-side, is prevented effectively from The generation of " abandon wind, abandon light " phenomenon, while in the case of Peak-valley TOU power price, being efficiently utilized by " peak load shifting " Electric energy and the electric electricity charge of degree for reducing user.Hot and cold, CCHP (Combined Cooling, Heating and Power, CCHP) development and application of technology, have also preferably promoted the development of multiple-energy-source microgrid, gas turbine and lithium bromide chiller Combination electric energy can not only be provided, moreover it is possible to heat energy and cold energy are provided the user by the cascade utilization of the energy, make " micro- electricity of narrow sense Net " is developed into " the micro- energy net " of broad sense.The energy resource structure and equipment coupled relation of micro- energy net of supply of cooling, heating and electrical powers are very Complexity, conscientiously studies it and provides multiple forms of energy to complement each other with coupling mechanism for the intelligent control of micro- energy net and optimization operation with particularly significant Practical significance.
At present, the research of micro-capacitance sensor has been achieved with certain progress, but it is also less to be related to the research of CCHP micro- energy net, It is concentrated mainly in terms of system model, operational efficiency and economy.By gas turbine, photovoltaic, breeze wind, storage The complementary micro-energy resource system of multi-source that the clean energy resourcies such as energy, earth source heat pump and renewable energy forms constitute collaboration optimization is got over To be more widely applied.
Current research all concentrates on a certain one-sided of micro- energy net, fails to grind from the operation progress analysis of whole system Study carefully.For problem above, herein with intelligent industrial garden by Natural Gas turbine, photovoltaic, wind-power electricity generation, ground source heat Based on micro- energy net of the clean energy resourcies such as pump, energy storage and regenerative resource composition, comprehensive analysis is carried out from efficiency angle.
The content of the invention
A kind of efficiency operation reserve for micro- energy of providing multiple forms of energy to complement each other, can effectively improve the comprehensive utilization ratio of the energy, reduce energy consumption Amount and operating cost, " electricity determining by heat " operational mode can realize the cascade utilization of the energy, in this mode, and System Priority is more than The waste gas that heat boiler is reclaimed freezes or heated to realize, realizes the comprehensive utilization ratio highest of the energy.
Now, the relation of the thermal demand of system and boiler afterheat yield is,
Qrec=Qreq=Qch+Qhc
Wherein, QrecFor the thermal energy of recovery, QreqFor the demand freezed with heating operations heat energy, QchAnd QhcRespectively make Heat energy needed for heat and refrigeration.Gas turbine consumption energy be,
QgtFor gas turbine energy input, ηgtFor gas turbine power generation efficiency, ηrecFor organic efficiency.The electric energy of gas turbine It is output as,
Egt=Qgt·ηgt
Electric energy exports total amount
Em=Egt+Ewt+Epv+Ebt
EmTotal amount, E are exported for system powergt, Ewt, EpvThe respectively electric energy output of gas turbine, blower fan, photovoltaic, EbtFor The electric energy charge and discharge amount of battery, ELFor system power load.
Work as Em> ELWhen, system works as E to bulk power grid power transmissionm< ELWhen, meet workload demand from bulk power grid power purchase.
According to heat (cold) workload demand on hot (cold) load prediction same day a few days ago.Hot (cold) the workload demand value of setting, system Generated electricity and heat supply according to heat (cold) demand regulating gas turbine of setting, ensure the demand of heat supply first.
Exerting oneself for combustion engine is controlled according to hot (cold) workload demand.
Electric energy deficiency is supplemented by civil power.
