Abstract

The invention provides a control method and device of a distributed power supply, and the method and device are suitable for the technical field of new energy. The method comprises the average, upper limit and lower limit of electricity price are calculated according to a predicted electricity price; if real-time electricity price is lower than or equivalent to the lower limit of the electricity price, charging power of an energy storage battery is set and a charging process is started; if the real-time electricity price is greater than or equivalent to the upper limit of the electricity price, discharging power of the energy storage battery is set and a discharging process is strated; and if the real-time electricity price is between the upper limit and the lower limit of the electricity price, the charging process and the discharging process of the energy storage battery are stopped. According to embodiments of the invention, the randomness and fluctuation of the distributed power supply are taken into consideration, the charging and discharging power of the energy storage battery is set by combining the predicted electricity price and the real-time electricity price, charging and discharging control for the energy storage battery is realized, intermittent energy absorption and optimization are realized, peak clipping and valley filling functions of the electrical network are realized, and the power utilization cost of users is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a control method and device of a distributed power supply. Background technique [0002] Facing the huge challenge of global energy conservation, emission reduction and energy sustainable development, vigorously developing distributed renewable energy power generation has become an inevitable choice. Therefore, the future development trend of smart distribution network is to realize the distributed power generation in the distribution network. Wide access and high penetration. [0003] The widespread access and high penetration of distributed power in the distribution network will form a regional microgrid. In the prior art, when the public connection point is incorporated into more than one power supply and load adjustable system with energy storage, it has not yet There is an effective control strategy to control controllable equipment such as user-side distribu...
