The invention discloses a local power supply dual-network distributed control system which comprises a power storage part and an adjusting and controlling part. The power storage part comprises a hydropower station, a plurality of additional power supply networks and a plurality of photovoltaic power generating stations. The adjusting and controlling part comprises a plurality of control units, the control units belongs to different user terminals, the control units correspond to the photovoltaic power generating stations in a one-to-one mode, the additional power supply networks are connected with the hydropower station, and power is supplied to the additional power supply networks through the hydropower station. A dual-network power supply system is formed by a mains supply network and the additional power supply networks, when power is normally used, the user terminals are connected into the mains supply network to carry out power supply, the control units control the photovoltaic power generating stations to be connected with the hydropower station, and pumped storage is carried out through the power of the photovoltaic power generating stations. In the peak demand period, the hydropower station generates the power through water level altitude differences of an energy storage reservoir, and the user terminals are switched into the additional power supply networks to carry out power supply. According to the local power supply dual-network distributed control system, the problem that the power is insufficient in the peak demand period is solved, and implementing guarantees are provided for the distribution operation and unified management modes of the solar power generation grid connection application of large-scale user groups.
Description
technical field [0001] The invention relates to a multi-network power supply related device, in particular to a local power supply dual-network distributed control system. Background technique [0002] In the grid-connected application of solar power generation, the method of integrating photovoltaic power inverting and boosting and integrating solar thermal power generation with boosting is generally adopted. The requirements are relatively strict, which requires the purchase of expensive equipment. However, the energy structure suitable for China's resources, geographical conditions and climate is precisely decentralized, not unified, and decentralized. In addition, in terms of electricity consumption time, peak hours appear with seasons and different time periods of the day, for example, air conditioners use more electricity as the temperature increases. All these inadvertently increase the complexity and instability of the entire power supply system. How to solve the p...
