Description
Technical field
The present invention relates to a kind of energy management and control system and method that tree is allocated based on two-dimentional bidirectional energy, belong to electricity
Power technical field of automation, is particularly suitable for use in the management of micro-capacitance sensor region energy and control field.
Background technology
Micro-capacitance sensor typically has multiple micro batteries, and such as wind-powered electricity generation, photovoltaic, diesel-driven generator, micro-capacitance sensor can also use biography
The electric power energy that the bulk power grid of system is provided.The energy management of micro-capacitance sensor should comprise at least following module with control system：Number
According to collection and monitoring, micro-capacitance sensor scheduling strategy and economical operation, micro-capacitance sensor state estimation, micro-capacitance sensor safety analysis etc..It is wherein micro-
Dispatching of power netwoks strategy and economical operation module determine micro-capacitance sensor how efficiently use distributed energy, how smooth switching
How various micro- sources and the operational mode of micro-capacitance sensor, ensure a series of problem such as the stability of micro-capacitance sensor.
The energy management of current micro-capacitance sensor typically uses master-slave control mode, many agentbased control patterns and right with control system
Etc. control model, but every kind of control model is the problem of all have certain.
Master ＆ slave control is exactly that some controller is worked as into host in the control system of micro-capacitance sensor, and other are from control
Generally required in correspondence between device, master-slave controller, and master controller is obeyed from controller.Master controller is detected in real time
Various electrical quantity in system, corresponding control measures are taken according to the operation control targe of micro-capacitance sensor, keep the voltage of micro-capacitance sensor
And frequency stabilization.There is following problem in master slave mode：(1) it is not easily accomplished distributed energy under micro-capacitance sensor master slave mode
The requirement of " plug and play "；(2) when main controlled node delays machine or controlled node and main controlled node communication failure, principal and subordinate
Pattern will be unable to the relation of distributed energy and load in rational allotment micro-capacitance sensor；(3) control limited speed is in main and subordinate node
Between traffic rate.
Multi-agent system is made up of multiple agencies by cooperating, and its elementary cell is agency, and agency can be with it
Place environment carries out interactive.Agency is made up of 3 functional layers：Management and organized layer, cooperation layer and execution level.Management and tissue
Layer mainly obtains object definition or inquiry, and relevant constraint, including executive plan, functional assessment and study.Coordinate
The task of layer be defined according to the basic process for coming Self management and organized layer, the execution of action step activation action；Cooperation layer can
To be extended to action, so as to be responded to event.Execution level is that a series of actions is performed, and followed by the inspection to action
Look into.There is following problem in many proxy modes：(1) need to customize each Agent special control strategy；(2) Agent it
Between for traffic rate requirement it is high, current existing means of communication is not easily achieved large-scale application；(3) Agent is one
Individual intelligent cell, the intelligent algorithm of use needs the accumulation of historical data, therefore the operation shape that an Agent is optimal
State needs longer time.
All distributed power sources that equity control refers in micro-capacitance sensor have between identical status, each controller in control
In the absence of master slave relation, voltage and frequency independent operating of each micro battery according to access point.Reciprocity control model shortcoming：
(1) during isolated power grid, a certain degree of deviation, and the error are constantly present between the voltage and frequency and its rated value of micro-capacitance sensor
It is difficult to eliminate；(2) because the size of resistance in micro-capacitance sensor be can not ignore for reactance, micro-capacitance sensor voltage is by wattful power
The influence of rate, frequency are influenceed also very significantly by reactive power, therefore using the Droop controlling parties of traditional droop characteristic
The sensitivity of method may be not ideal enough.
Each node in two-dimentional energy allotment tree contains the energy pass of micro-capacitance sensor wind-powered electricity generation, photovoltaic, energy storage, load
It is corresponding that energy system in key word, region micro-capacitance sensor, sub- microgrid and micro-capacitance sensor allocates each layer set with energy.Each energy
Node is measured to interconnect with its father node, child node and the left and right brotgher of node.The advantage of this framework method is can be effectively dynamic
The change of distributed power source and load in micro-capacitance sensor is managed, because increasing under this framework or deleting a node, is only influenceed
Former node and father node, without influenceing sibling, space utilization rate is higher；On the other hand, it can be carried out between father and son's node
Random energies are allocated, and order energy allotment can be carried out between the brotgher of node, and the two-way dispensing mode of this two dimension can be carried
High-energy temporarily transfers rate in the effective life of configuration.
The content of the invention
The purpose of the present invention be overcome the shortcomings of prior art exist there is provided based on two-dimentional bidirectional energy allocate set energy
