Description
Technical field
The present invention relates to a kind of generation schedule coordination optimizing method is and in particular to a kind of broad sense gets in touch with the off line province of ray mode two
Level real-time generation schedule coordination optimizing method, the invention belongs to dispatching automation of electric power systems technical field.
Background technology
Currently, iterative method and enforcement are built with intelligent grid, according to the prediction of next day need for electricity it is considered to system balancing
The various constraintss such as constraint, unit operation constraint, operation of power networks constraint, optimize establishment 96 points of Unit Combination plans of next day and go out
The practical function degree of generation schedule a few days ago of power plan steps up.A few days ago operation plan support energy-saving distribution, electricity market,
Three 3 kinds of scheduling methods of public scheduling, on the premise of load prediction data possesses, generation schedule function can be used in establishment time a few days ago
The Unit Combination plan of day to following many days and the plan of exerting oneself, the period interval of generation schedule is 15 minutes a few days ago, daily start-stop
Time is 00:15～next day 00:00.Generation schedule can be planned and unit output plan in the combination of automatic computing engine group a few days ago,
Consider transmission cross-section security constraint in planning, specify transmission of electricity element security constraint, ground state security constraint and n-1 safety about
Bundle, supports generation schedule a few days ago is carried out ground state trend check and n-1 Security Checking.
Plan in practical implementation a few days ago, because system loading prediction a few days ago and new forms of energy prediction a few days ago are deposited with actual
In relatively large deviation, lead to the plan of a few days ago exerting oneself significantly to adjust, adjust to AGC unit and bring immense pressure, also reduce simultaneously
Power grid security index.For solving this problem, real-time generation schedule establishment is brought into schedule, and real-time generation schedule programmed function is according to
New power system operating mode change, operating states of the units change, super short period load requirement forecasting, the prediction of ultra-short term new forms of energy, real
When cross-section limitation and being planned by electricity, with reference to generation schedule a few days ago, work out the unit generation plan of following multiple periods.Real-Time Scheduling
Energy-saving distribution, electricity market, three 3 kinds of scheduling methods of public scheduling are supported in plan, and the period interval of real-time generation schedule is 5 minutes
（Or 15 minutes）, the time range of planning is following 1 to a few hours, and the initial time period of calculating is that 15 minutes futures are corresponding
Period.Such as current time is 10：15 points, then the real-time generation schedule time range worked out includes 10：30 points～11：30 points,
Plan in every 5 minutes is exerted oneself.Can the plan of exerting oneself of automatic computing engine group, but Unit Combination state is not adjusted, that is, only
Including Unit Economic scheduling feature, do not include Unit Combination function, planning considers transmission cross-section security constraint, specifies
Transmission of electricity element security constraint.
Planning basic data accuracy height in real time, ultra-short term prediction data and real data deviation very little, meter of exerting oneself
Draw implementation rate increase substantially, while being that AGC eases off the pressure, more can the operation of power networks of accurate evaluation future 1 to a few hours peace
Quan Xing.
However, there is deficiency as follows in prior art：Each province's electricity consumption, by saving key pipe unit and the offer of net key pipe unit, saves
Adjust real-time planning and the net real-time planning of tune to be two autonomous systems, province adjusts real-time planning function layout to save and adjusts again
Adjust pipe unit, real-time planning function layout net key pipe unit adjusted by net, net saves adjusts real-time planning function independently
Arrange each self-regulated pipe unit plan, jointly meet provincial need for electricity, how net realizes the coordination of real-time planning between saving, such as
What adjustment saves key pipe unit and exerts oneself plan and save straightening and belong to net key pipe unit output plan it is ensured that net saves to adjust counts in real time a few days ago
Draw coordinated operation, prior art can not solve this problem.
Content of the invention
