The invention discloses a
photovoltaic power generation and rod pumped well group off-peak power utilization
coupling control method, and relates to the technical field of oilfield development and
new energy utilization. The method comprises the following steps of: acquiring data such as photovoltaic power,
irradiance, temperature,
wind speed, an
indicator diagram of a pumping unit, electrical parameters, a
working fluid level and
stroke frequency, and constructing a multi-
modal data set comprising external meteorological characteristics, a shaft
operation time sequence and a well group space relationship; a
time sequence model combining reversible normalization and cross-variable attention is adopted to predict photovoltaic output, and a multi-mode liquid supply
state recognition model is utilized to obtain the liquid supply sufficiency level of each well. On the basis, a peak shifting
power consumption optimization model which takes minimum
energy consumption and light abandoning quantity as targets and meets the requirements of yield,
power grid capacity, start-stop times and liquid supply constraint is constructed,
reinforcement learning is introduced to generate well group start-stop and
stroke frequency strategies, and dynamic matching of photovoltaic output and pumping
unit load is realized according to real-
time data rolling updating, so that the optimal
power consumption is realized. The photovoltaic
utilization rate is improved; and the
energy cost is reduced.
