Energy-optimised management, is one of principal character of intelligent grid.The principal contradiction of energy-optimised management is to power
Company produces has greatest differences in electric power and all types of user consumption electric power time scale.All types of user determines according to self-demand
Consumption habit and electricity consumption load curve, such as factory determine the flow work situation, business premises root according to production procedure and plan
Determine room power consumption condition according to company work system and office worker's job placement, domestic consumer determines to use according to life and consumption habit
The working condition of electric equipment, City Rail Transit System mainly has for the impact of user's request according to the energy-optimised management of traffic
Two classes:1) reduce user power utilization demand;2) user power utilization demand is shifted on time scale.Energy-optimised management strategy mainly has
Two big class:1) response policy based on excitation;2) response policy based on price.Wherein warp is used based on the response management of price
Important tool in Ji, such as pricing strategy are so that the response of user's request disclosure satisfy that system reliability, energy using effectively
Property, the requirement of security, all pricing strategies be based on this assume:The need for electricity of all types of user is had with the electricity price in electricity consumption moment
And its close negative incidence.Energy-optimised management refers to the energy management strategies that network system manager and user adopt, and reduces
Electrical demand peak average value ratio, improves energy ecology and the reliability of electrical network.Research Requirements side response management problem
The service efficiency of the energy will be improved, reduce Peak power use amount, improve the safety and stability of electrical network.In intelligent grid system
In, the construction of bidirectional communication network will be helpful to the data of grid management centre collection perception electricity consumption side, for arranging production, passing
Defeated, distribution decision provides reliable data to support, improves production and the efficiency of transmission of the energy, intelligent power distribution architectures of communication networks is such as
Shown in Fig. 1.
In sum:On the premise of not changing existing adapted electrical network infrastructure construction, energy-optimised management is for joining
Embody, with the significance of electrical network, the steady safe operation being to ensure electrical network, improve reliability and stability it is therefore necessary to
Set up efficient energy ezpenditure Method for optimized planning, the Operating ettectiveness of lifting intelligent grid.
