Embodiment
As shown in the figure, the present invention includes energy part, transmission of electricity part, power transformation part, intelligent scheduling part, distribution section and electricity consumption part, it is characterized in that, Ministry of Energy divides and comprises thermoelectricity, water power and new forms of energy, energy part by transmission of electricity part by power delivery to power transformation part, after current/voltage adjusts by power transformation part under the effect of intelligent scheduling part through distribution section carry electricity consumption part.
As a kind of preferred version, described intelligent scheduling part regulates transmission of electricity part, regenerative resource part and distribution section, regenerative resource enters distribution section after intelligent scheduling partial adjustment after transmission of electricity part power transformation part, preferably supplies electricity consumption part.
Intelligent grid, is often referred to new network system contemporary information systems being incorporated traditional energy network formation.Thus make electrical network have better controllability and ornamental, solve the problem such as low, the interactive difference of conventional electric power system energy utilance, security and stability analysis difficulty; Simultaneously based on the real-time monitoring of energy flow, be convenient to distributed new generating, the access of distributed energy storage system and use.1st distinguishing feature of intelligent grid is that ornamental is strong.Namely by information network technique, the information of each node of real-time electric power monitoring system.The 1st level that such as IBM defines intelligent grid 3 levels be exactly " realize to operation of power networks state, asset equipment state and client's power information real-time, monitor comprehensively and in detail; eliminate monitoring point ", think that intelligent grid is that two nets of conventional electric power system network and Electricity Information Network merge and interact.
Utilization rate of equipment and installations is improved while intelligent grid principal security power grid security, stable and reliability.Due to the coupling of network system height, scheduling controlling is improper, and single failure can cause cascading failure, even causes large area blackout and device damage, thus causes immeasurable direct and consequential damage, therefore network system is very high for the requirement of reliability.The intelligent scheduling of intelligent grid is exactly to ensure safe and reliable basis solve the collection of Wide-area Measurement Information, transmission, treatment and analysis problem.Realize the interaction of generating and electricity consumption.The essential characteristic of electrical network is the balance of generating and electricity consumption.From the angle of terminal use, user can get the operational factor of electrical network by intelligent electric power terminal, thus adjusts the electricity usage situation of oneself.And for network system, then can build accurate load model according to the power information of power consumption equipment, effectively improve power supplying efficiency.The construction of tradition electrical network based on sending out-defeated-become-join-unidirectional thinking, bulk redundancy causes waste, intelligent grid is based on the measurement communication system of real-time higher (a few tens of milliseconds level), can by controlling in real time to reach generation load balance, thus stand-by heat can be reduced, and improve the stability of system.
The access of batch (-type) regenerative resource.New forms of energy mainly refer to wind-powered electricity generation and photovoltaic generation, and the wind power resources of China mainly concentrates on northwestern, and these areas are also the more rich areas of solar energy resources equally.The area that Electricity Demand is larger then concentrates on the central and east, therefore causes the new forms of energy electric power of China to necessarily pass long-distance transmissions and could arrive loading zone.This just requires that electrical network must be optimized configuration to generation of electricity by new energy in China.Meanwhile, because generation of electricity by new energy itself has randomness and intermittent feature, if be directly incorporated into electrical network, then the stability of network system entirety may be affected.As wind power generation due to objective meteorological reason off-grid on a large scale, may will cause the imbalance that electric power system is instantaneous, then affect overall stability.
