چکیده انگلیسی:
Due to environment-friendliness, renewable energy like solar power and wind power is more and
more introduced to energy systems all over the world. Simultaneously, high penetrations of wind
and solar generation also have brought severe curtailment of wind and solar. How to alleviate
curtailment of wind and solar is a crucial problem in evaluating accommodation capability of
renewable energy, which reflects the extent of utilization of renewable energy and economic benefits.
The uncertainty of renewable energy brings challenges to precisely describe renewable generation,
which leads to difficulty in designing effective mechanisms for accommodation capability of renewable
energy. Existing work suffers from high computation overhead from frequently updated data, and
low precision of describing renewable energy, which leads to less effective policies for renewable
energy accommodation and underestimated accommodation capability. To make the most of renewable
energy, an algorithm AccCap-DRL based on deep reinforcement learning is proposed. AccCap-DRL
partitions a distribution into segments by time intervals, employs WGAN to describe distributions
of renewable energy data, and employs DDPG to obtain approximate policies for renewable energy
accommodation in different scenarios. Simulation results from real power generation and users’
demand data show high effectiveness of the proposed algorithm, and high efficiency of evaluating
accommodation capability.
