The invention discloses an active power distribution network fault recovery method and device, equipment and a storage medium, relates to the technical field of power systems and automation thereof, can accurately identify fault properties on the basis of identifying the fault types, and improves the power supply reliability and adaptability of a power distribution network under new energy access. The method comprises the following steps: acquiring fault point current information and / or fault point voltage information output by a distributed power supply in an island state of the active power distribution network; fault type identification is carried out on the fault point according to the fault point current information and / or the fault point voltage information, fault types are obtained, and the fault types at least comprise a low-resistance grounding short circuit fault, a high-resistance grounding short circuit fault and an interphase short circuit fault; carrying out fault property identification on the fault category to obtain a fault continuous feature; and determining a fault recovery strategy according to the fault type and the fault continuous characteristic, and carrying out fault recovery on the active power distribution network through the fault recovery strategy.

A method, system, product, and medium for coordinated control of distributed power sources are disclosed. The method includes: real-time detection of the power output decline rate of photovoltaic power plants and wind turbines, current grid load data, power demand, and the remaining capacity and discharge power of energy storage batteries; under high-risk conditions, calculating the real-time load characteristics of each load and prioritizing all loads; isolating non-critical loads ranked in the priority order within a preset low percentage range from the main grid and issuing isolation notifications to their load sides; when insufficient power is detected, injecting electrical energy into the grid by controlling the power supply or discharge status of controllable loads; calculating the current power gap, and controlling the start-up of inactive generator units when the power gap exceeds a preset threshold. Implementing the technical solution provided in this application improves the dynamic response capability of the power grid under distributed power fluctuations and load surges.
