Description
Technical Field
The invention belongs to the technical field of micro-grid energy storage, and particularly relates to micro-grid-based power energy storage equipment and method and a computer program instruction medium for realizing the method.
Background
The micro-grid is a new grid structure, and is concerned by more and more scholars and research institutions in many countries and regions. A microgrid is considered a small electrical system comprising generators, loads and storage devices. The access of distributed power sources to a power distribution network in the form of a microgrid has become one of the ways to effectively utilize distributed power sources. The development of the micro-grid is beneficial to introducing a large amount of renewable energy sources, so that the power system becomes more reliable, safe, clean and economical. The combination of the micro-grid and the large-scale grid can guarantee power supply in a very period, and meanwhile, the micro-grid can optimize the operation mode of the grid, reduce pollution to the environment and meet the sustainable development strategy of fully developing and utilizing renewable energy sources and developing low-carbon economy in China.
Alternating current micro grids (AC-MG) have been widely studied, however, only a single AC power supply is used to supply power to the system, which not only increases the system cost and loss, but also brings corresponding harmonic problems. With the increasing direct current type distributed power sources and direct current loads in micro-grids, scientists have proposed a direct current micro-grid (DC-MG). The dc microgrid is a device that uses a dc power source to cluster dc loads to minimize ac to dc conversion losses. Alternating current and direct current micro-grids are connected through one or more Interconnection Converters (ICs) to form an alternating current/direct current Hybrid micro-grid (HMG).
The AC-DC hybrid micro-grid well avoids a plurality of problems caused by the fact that multiple times of current conversion are needed when DGs and loads are connected into the AC micro-grid or the DC micro-grid. The alternating current-direct current hybrid micro-grid can be selectively accessed to the alternating current or direct current micro-grid according to the output characteristics of each distributed power supply, the installation number of power electronic converters is reduced, the energy output efficiency of each power generation unit is improved, and the harmonic content in electric energy can be reduced while the intermediate conversion link is reduced.
The chinese patent application with application number CN202011322270.6 proposes a hybrid microgrid energy distribution method and system considering energy storage operation constraints, the method includes: the method comprises the steps of predicting the output power of a wind power plant, predicting the output power of a photovoltaic power generation unit, predicting the power required by a load, solving a microgrid energy distribution optimization objective function under a dynamic operation constraint equation of an energy storage battery system, and performing energy distribution on the microgrid by combining the solution result of the optimization objective function and the predicted output power of the wind power plant, the output power of the photovoltaic power generation unit and the power required by the load.
The chinese patent application with application number CN202011312419.2 proposes a hybrid linear economic planning method for an energy storage hybrid microgrid, which comprises: establishing a solar cell panel output power decomposition type, a wind turbine generator output power decomposition type and an energy storage system charge and discharge power expression through a hybrid linear economy planning framework; defining the battery pack charging and discharging limit in the energy storage system charging and discharging power expression; establishing an energy storage hybrid micro-grid power configuration equation containing power consumption variables; establishing a total cost equation of the kth component of the hybrid energy storage microgrid; defining a capital recovery factor; obtaining the annual initial cost of the kth component, the annual reset cost of the kth component and the residual value of the kth component; obtaining the annual unit cost of the hybrid system component, and further obtaining the net current cost of the kth component; obtaining the total net cost of the energy storage hybrid micro-grid; and analyzing the total net cost of the energy storage hybrid micro-grid, and improving the economy of the energy storage hybrid micro-grid by applying a hybrid linear economy planning method.
However, the inventor finds that the prior art mostly adopts global overall target control for the hybrid microgrid without considering the structural characteristics and power output of different microgrids, so that the system stability and balance of the hybrid microgrid and the electric energy storage utilization rate are to be further improved.
