The process flow diagram of the electrically optimized Potentials method of electric power demand side that Fig. 1 provides for the embodiment of the present invention, actual conditions according to each user are analyzed the load optimal potentiality of user and node optimization potentiality, obtain user power utilization according to load optimal potential value and economize on electricity Optimized Measures and optimize Potentials result, make to optimize further with the electricity consumption Optimal Configuration Method of electrically optimized Potentials result to user according to this, make the management of power use of several user further close to the management of power use upper limit that this user can bear; With reference to Fig. 1, the electrically optimized Potentials method of this electric power demand side can comprise:
Step S100: according to electricity consumption configuration scheme and the electricity consumption data of user under described electricity consumption Optimal Configuration Method of user, obtains the theoretical load curve of described user under described electricity consumption configuration scheme and realized load curve;
Due to reality implement the scheme of electricity consumption configuration scheme time, the facility, the operating power of equipment and the equipment that use due to user generate the otherness of working time etc., and user crosses realized load curve that general electrically optimized allocation plan obtains and will inevitably there is certain otherness by the theoretical load curve that this electricity consumption configuration scheme obtains.
Optionally, can according to after the electricity consumption configuration scheme determining user, the theoretical load curve of this user under described electricity consumption configuration scheme is obtained according to the electricity consumption configuration scheme of this user, after obtaining the electricity consumption data of this user under described electricity consumption Optimal Configuration Method, obtain the realized load curve of this user under this electricity consumption configuration scheme according to described electricity consumption data.
Optionally, due to according to the electricity consumption configuration scheme of user and the electricity consumption data of user under described electricity consumption Optimal Configuration Method, before obtaining the theoretical load curve of described user under described electricity consumption configuration scheme and realized load curve, need the electricity consumption configuration scheme first learning user, therefore, if according to the electricity consumption configuration scheme of user and the electricity consumption data of user under described electricity consumption Optimal Configuration Method, the electricity consumption configuration scheme of user is not learnt before obtaining the theoretical load curve of described user under described electricity consumption configuration scheme and realized load curve, then need the electricity consumption configuration scheme first obtaining user.
Optionally, by being target with economic benefit, objective function can being set up according to predetermined constraints condition, obtaining linear electricity consumption Optimized model, then carry out electricity consumption according to described linear electricity consumption Optimized model to user to distribute rationally, obtain the electricity consumption configuration scheme of this user.
Step S110: according to described theoretical load curve and described realized load curve, determine that there is the time range by electrically optimized potentiality, and the difference calculated in described time range between each time point actual negative charge values and theoretical negative charge values, obtain the load optimal potential value of each time point;
If the theoretical negative charge values on the theoretical load curve of certain time point is lower than the strength load value on realized load curve, then illustrate, on this time point, lower load can also be had, and this point has and uses electrically optimized potentiality, and the time range had by electrically optimized potentiality, be then all set with time point by electrically optimized potentiality.
Optionally, by described theoretical load curve and described realized load curve are placed in the same coordinate system, the point of crossing of described theoretical load curve and described realized load curve can be determined; If realized load curve is positioned at the top of theoretical load curve between adjacent two point of crossing, then between two crunodes of being separated by described in thinking, the described time range determined is have the time range by electrically optimized potentiality.
