Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Distributed photovoltaic consumption system embodiment:

[0028] This embodiment provides a distributed photovoltaic accommodation system, which can accommodate more photovoltaics and reduce the light rejection rate while ensuring power quality.

[0029] Such as figure 1 As shown, the distributed photovoltaic consumption system of this embodiment includes a three-phase thermal storage electric boiler, a single-phase thermal storage electric boiler, an energy storage system, a single-phase photovoltaic inverter and a commutation switch. Among them, the three-phase regenerative electric boiler is used to connect the low-voltage side busbar of the transformer in the station area; the energy storage system is used to connect the low-vo...

Abstract

The invention provides a distributed photovoltaic accommodation method, system and computer-readable medium, which belong to the technical field of photovoltaic accommodation. The method includes the following steps: when the three-phase AC bus has unbalanced three-phase loads, find out the heavy-load phase and the light-load phase; Type electric boiler, switch the single-phase regenerative electric boiler to the light-load phase; after the switch is completed, re-judge whether the three-phase load imbalance still exists, if not, the three-phase load imbalance adjustment is successful; if it exists , then re-find the current heavy-load phase and light-load phase, and repeat the switching process of the single-phase thermal storage electric boiler. On the premise of ensuring the power quality, the present invention avoids the light abandonment caused by limiting the output of the photovoltaic inverter or cutting the photovoltaic inverter from the branch circuit, reduces the light abandonment rate, and can accommodate more photovoltaics.

Description

technical field [0001] The invention relates to a distributed photovoltaic accommodation method, system and computer-readable medium, belonging to the technical field of photovoltaic accommodation. Background technique [0002] At present, a large number of single-phase distributed poverty alleviation photovoltaics are connected to some rural distribution networks. Due to the randomness of photovoltaic output, the high penetration rate of a large number of single-phase distributed photovoltaics has become the main reason for power fluctuations in low-voltage station areas; in addition, Rural agricultural load capacity is insufficient, and the loads are mostly household loads such as lighting and cooking power and productive loads such as feed machines, and the power load is greatly affected by natural conditions such as climate and seasons, and it is very easy for photovoltaic output to not match the load . However, the randomness of photovoltaic output and its dynamic mism...
