Background technology
Regenerative resource includes water energy, biomass energy, wind energy, solar energy, geothermal energy and ocean energy etc., and resource potential is big,
Environmental pollution is low, can continuous utilization, be advantageous for harmony between man and nature development important energy source.In addition, natural gas conduct
Clean energy resource is also widely used in domain type distributed energy resource system.For at present to hot and cold, electric, gas various energy resources
Demand, the system of providing multiple forms of energy to complement each other are arisen at the historic moment.System of providing multiple forms of energy to complement each other is exactly to be complemented each other, comprehensively utilized using the above energy, so as to
Energy output and utilization ratio are improved, meets hot and cold, electric, gas the energy demand of user.
National Development and Reform Committee, Bureau of Energy are for system of providing multiple forms of energy to complement each other, it is proposed that more perfect definition：First, terminaloriented is used
A variety of energy demands, the optimization layouts such as family is hot, cold, electric, gas build integrated energy supply infrastructure, realize multipotency collaboration confession
Should be with Integrated Energy cascade utilization；Second, utilize the money such as large-scale synthesis Energy Base wind energy, solar energy, water energy, coal, natural gas
Source combination advantage, honourable extreme misery is promoted to store up system Construction operation of providing multiple forms of energy to complement each other.
System of providing multiple forms of energy to complement each other is suited measures to local conditions with it, gathered materials on the spot, answering the characteristics of user's request custom design, is had wide
Application space.Because the building form for the system of providing multiple forms of energy to complement each other is varied, comprising different resource forms and with can object, system
Operation reserve need to be formulated in light of the circumstances.
CN 105305495 A《A kind of multi-energy complementary micro-grid system scheduling method》Mainly for wind and light generating system, combustion
Gas generator, energy-storage system, the micro-grid system dispatching method of electronic charging station, it is not directed to export hot and cold, electric various energy resources system
The related operation of system and control method.CN 105356573 A《Multi-energies hybrid power generating system and power supply distribution method》Also only

Specific system running policy.
The content of the invention
The purpose of the present invention is to propose that one kind is provided multiple forms of energy to complement each other system universal operation method the shortcomings that overcoming prior art.
The present invention realizes each distributed energy, energy storage, load by the formulation of the universal operation reserve of the system of providing multiple forms of energy to complement each other
Effective control and management, it is ensured that energy supply and the balance of workload demand in system of providing multiple forms of energy to complement each other, realize that the optimization of various energy resources is adjusted
Degree, guarantee system of providing multiple forms of energy to complement each other are in economical operation state steady in a long-term.
Technical scheme is as follows：
A kind of system of providing multiple forms of energy to complement each other of the universal operation method of system of providing multiple forms of energy to complement each other of the present invention is broadly divided into two major classes：It is a kind of
Be it is cold and hot be electrically coupled the system of providing multiple forms of energy to complement each other, one kind is that cold and hot electrolysis coupling is provided multiple forms of energy to complement each other system.Wherein cold and hot be electrically coupled is provided multiple forms of energy to complement each other
System typically more includes alliance subsystem, such as combustion gas combined supply system, biomass co-feeding system, and other hot and cold, electric energy
Export independent particle system：Such as heat pump, photovoltaic generating system, solar-thermal generating system, wind generator system, energy-storage system etc.
It is combined, i.e., in this kind of system of providing multiple forms of energy to complement each other, hot and cold, electric energy output has height coupling, and its operation reserve is relatively multiple
It is miscellaneous.Cold and hot electrolysis coupling is provided multiple forms of energy to complement each other system, and hot and cold, electric energy output is respectively by different subsystems：Heat pump, photovoltaic hair
The combinations such as electric system, solar-thermal generating system, wind generator system, energy-storage system are realized, between each other substantially without coupling, each subsystem
Controlled between system relatively independent, simple.
The cold and hot system of providing multiple forms of energy to complement each other that is electrically coupled is because the output of cold and hot electric energy has height coupling, therefore operation reserve is divided into
" electricity determining by heat " and " with the fixed heat of electricity " both of which.Operation reserve under each pattern needs all in accordance with user whether there is heat supply or refrigeration
Ask two kinds of application scenarios different, while under every kind of application scenario, consider the situation whether power network normally accesses.Cold and hot electrolysis
Coupling is provided multiple forms of energy to complement each other system, substantially without coupling between subsystems, therefore is controlled relatively independent.Operation reserve distinguishes user whether there is
Two kinds of application scenarios of heat supply or refrigeration demand, while under every kind of application scenario, consider the situation whether power network normally accesses.
The present invention combines policy, each heat supply, cold, electronic system function, operation characteristic, to each of the system of providing multiple forms of energy to complement each other
Subsystem carries out coordination control, and guarantee is provided multiple forms of energy to complement each other, and system is stable, safe efficient, economical operation.
The system operation method of providing multiple forms of energy to complement each other of the present invention is specific as follows：
1st, it is cold and hot to be electrically coupled system running policy of providing multiple forms of energy to complement each other：
" electricity determining by heat " pattern, user have under heat supply or refrigeration demand occasion, when power network is normal, start cold and hot be electrically coupled
Other individually heat supply or refrigeration subsystems, whole cold and hot with preferential satisfaction in alliance subsystem and system in system of providing multiple forms of energy to complement each other
Based on heat supply or the refrigeration demand for being electrically coupled the system of providing multiple forms of energy to complement each other, the electric energy that alliance subsystem is sent can give user's electric load to supply
Electricity, now need to consider whether the electric energy that alliance subsystem is sent allows to surf the Net.If the electric energy sent does not allow to surf the Net, preferentially
