Description
Technical field
The present invention relates to a kind of system in distribution network planning field, specifically a kind of photovoltaic generation accesses power distribution network scheme and sets
Meter and analysis and evaluation accessory system.
Background technology
Photovoltaic generation to Optimization of Energy Structure, promotes energy-saving and emission-reduction, realization society as the Main Means of Solar use
Sustainable economic development are significant.With the successive appearance of relevant policies and technical standard, domestic grid-connected photovoltaic capacity
The trend for steeply rising is presented in recent years.Large-scale distributed photovoltaic accesses power distribution network, by the planning operation of conventional electrical distribution net
Influence is produced Deng many-side, it is double that conventional electrical distribution net translates into the two-way flow characteristic with trend, the load of user and power supply
Weight role, the probabilistic New Active power distribution network of the both-end of load and power supply, so as to cause the analysis and evaluation of conventional electrical distribution net
Instrument is no longer applicable completely, such as external CYMDIST（The distribution system analysis system of CYME Distribution, CYME companies）、
ETAP（The electric power electric analysis of ETAP companies, electric energy management Comprehensive Analysis Software system）、DPlan（Distribution
Planning, distribution network planning system）Function Deng offer belongs to traditional distribution system analysis function, does not account for distribution
The characteristics of distributed energy is largely accessed in net.Existing new energy design tool such as U.S.'s regenerative resource laboratory（NREL
, National Renewable Energy Laboratory）The microgrid economic analysis instrument HOMER of exploitation（Hybrid
Optimization of Multiple Energy Resources, multiple-energy-source hybrid optimization system）, German power system point
Analysis software DIgSILENT（Digital Simulation and Electrical Network, Digital Simulation and power network are calculated
System）And special photovoltaic system is analyzed and design tool PVsyst（PhotoVoltaic system, photovoltaic system design
Software）、PV*SOL（PhotoVoltaic Solar, solar energy photovoltaic system design software）Deng biasing toward photovoltaic plant body
The operation sunykatuib analysis of Computer Aided Design and photovoltaic generation, can not run through the overall process that photovoltaic accesses engineering assistance design work,
The photovoltaic carrying capacity from the power network entirety angle whole power distribution network of measurement is not supported, and can not compatible country's distribution web information system
And the characteristics of data.
The domestic new energy with photovoltaic as representative accesses demand main table of the power distribution network real work to aid at present
Now：
1）The demand of power distribution network design aids is accessed to photovoltaic
It is current domestic when photovoltaic access power distribution network conceptual design is carried out, generally it is required for first screening extraction power distribution network correlation
Related data in information system, is then converted into the form of the tool demands such as PVsyst, PV*SOL, in addition it is also necessary to be applied in combination many
The instrument of kind is not easy to photovoltaic and accesses the extensive of power distribution network conceptual design work to realize the function that Computer Aided Design, scheme are evaluated
Carry out.Power distribution network design aids is accessed it would therefore be desirable to have special photovoltaic, photovoltaic is extended not only through and is accessed engineering assistance design
The overall process of work, and the characteristics of compatible country's distribution web information system and data, Utilities Electric Co. can be directly embedded into and showed
In some distribution system analysis instruments.
2）To the demand of Time-Series analysis
Conventional electrical distribution net analysis tool is typically using the analysis method based on a certain typical time period section, such as distribution network planning
Generally it is analyzed using the state at peak load moment.And photovoltaic generation have interval, it is random the characteristics of, it is exerted oneself certain
In the range of continued jitters, thereby increases and it is possible to drastically change in a short time.If be still based on single using conventional electrical distribution net analysis tool
The analytical form of discontinuity surface, will likely produce the analysis result of mistake, it is therefore necessary to carry out using Time Series Analysis Method
More careful analysis and evaluation.
Described " Time-Series analysis ", is referred to various time scales（As it is single when discontinuity surface, 1 year, 1 day, 1 hour
Deng）Calculate the system of analysis and exert oneself time series data possessing power network sequential service data, photovoltaic power generation apparatus, it is necessary to be set up
On basis etc. detailed time series data.
With the lifting and the development of mass data storage technology of acquisition speed, the time series data of power distribution network is gathered
It has been achieved with storage, the Time-Series analysis of Study on Power Grid Planning aspect can be realized completely, and conventional electrical distribution net point
Analysis instrument does not utilize these data well.
3）To the demand of active power distribution network comprehensive assessment
After photo-voltaic power supply accesses power distribution network on a large scale, operation of power networks state will be because of a large amount of photo-voltaic power supplies with randomness
And become increasingly complex.Because the influence that photo-voltaic power supply is caused to power distribution network is not the simple folded of each photo-voltaic power supply influence
Plus, it is necessary to from the overall angle of power distribution network, many analyses are carried out to power distribution network on the basis of Time-Series analysis, so that effectively
The adaptability that is accessed to photo-voltaic power supply of assessment power distribution network and the ability of receiving, and with this instruct photovoltaic access power distribution network planning,
