Power generation scheduling technology involving time-related renewable energy in microgrid

Abstract

The invention discloses a power generation scheduling technology involving time-related renewable energy in a microgrid. The technology is mainly used for solving the problem of high costs of energy generation in microgrids. For solving the problem of the characteristics of randomness, discontinuity and instability of solar power generation, a novel flexible uncertainty model of the invention is designed; mean and second-order moment information is acquired through historical data of solar power generation quantity, and thus a moment counting uncertainty set is defined to limit fluctuation ofactual solar power generation quantity; time dependence of the solar power generation quantity is considered; and finally, an energy-saving power generation scheduling strategy is designed, a batteryis used as much as possible to supply power for users in order to consume lowest electric costs, and purposes of saving energy and protecting environments are achieved.

Description

technical field [0001] The invention belongs to the technical field of renewable energy, and in particular relates to a power generation scheduling technology involving time-related renewable energy in a microgrid. [0002] The invention discloses a power generation scheduling technology involving time-related renewable energy in a microgrid, which is mainly used to solve the problem of high cost of energy generation in the microgrid. The present invention takes into account the two characteristics of the micro-grid, one is the integration of large-scale renewable energy, that is, deploying a large number of solar photovoltaic panels, which can be powered by solar energy, and the other is that it is equipped with a power storage system (battery), that is, it can store The power generated by solar energy, and the electricity produced by solar energy will be given priority to charge the battery. In addition to the battery, the microgrid can also provide power for home users thro...

Problems solved by technology

The two characteristics of the microgrid are the utilization of large-scale renewable energy and the provision of energy storage systems. However, these characteristics not only bring huge economic and environmental benefits to the microgrid, but also bring great benefits to the design of intelligent control strategies for the microgrid. great challenge

Traditional power generation dispatching schemes are usually based on the high predictability of energy generation, that is, the amount of power generated by the traditional grid is predictable and controllable. However, when using renewable energy, which is a highly unstable and unpredictable power generation method, the traditional The power generation scheduling scheme is useless

Although the integrated energy storage technology can alleviate the uncertainty caused by the volatility of renewable energy to a certain extent, the operation and scheduling of the entire system is still very complicated.
