Abstract

The invention discloses a method for dispatching multi-time-scale energy of micro power grids on the basis of real-time electricity price mechanisms. The method for dispatching the multi-time-scale energy of the micro power grids on the basis of the real-time electricity price mechanisms includes day-ahead dispatching time scales and intra-day dispatching time scales. Priority dispatching strategies are connected with the day-ahead dispatching time scales and the intra-day dispatching time scales, and robust optimization problems can be solved for multiple time scales of the micro power gridsby particle swarm optimization algorithms. The method has the advantages that requirements of the real-time electricity price mechanisms can be met, the method is applicable to peak and valley time-of-use electricity price systems and includes concise steps, real-time and definite dispatching priority can be provided for various distributed power sources in the micro power grids in each dispatching time frame, renewable energy can be sufficiently utilized, wind and light abandoning can be reduced, and the load power supply reliability can be improved; dispatching strategies on the basis of real-time electricity price information and multi-time-scale theories are combined with one another, accordingly, intra-day dispatching guiding effects of day-ahead dispatching can be enhanced, coordination and matching of dispatching of two time scales can be promoted, and burden due to short-time-scale dispatching can be relieved.

Description

technical field [0001] The invention relates to the technical field of microgrid energy management, in particular to a microgrid multi-time scale energy scheduling method based on a real-time electricity price mechanism. Background technique [0002] In recent years, wind and solar energy have been widely used in the field of power generation, and the installed capacity of wind and solar power has increased year by year. However, the randomness and volatility of wind and solar energy profoundly affect the accuracy of scheduling. [0003] The time-of-use electricity price mechanism is a kind of electricity price system that has been widely used in my country in recent years. According to the load demand of users, the daily time is divided into peak-valley flat or peak-valley periods, and the optimal scheduling method based on the peak-valley time-of-use electricity price mechanism needs to rely on The division of peak and valley periods. [0004] Compared with the peak-valle...
