Stochastic power management strategy for optimal day-ahead scheduling of wind-HESS considering wind power generation and market price uncertainties

Marzieh Khosravi et al.

Summary: This paper proposes a stochastic framework for power management of a wind-hybrid ESS (HESS) to maximize the DA market profit through bidding a scheduled power, based on a mixed-integer linear programming. By considering uncertainties in wind power generation and DA market prices, scenarios are generated using Monte-Carlo method and roulette wheel, while ensuring the state of charge of HESS stays within a safe range. This approach aims to submit power to the DA market with no deviation and increase profit.

Stochastic short-term scheduling of a wind-solar-hydro complementary system considering both the day-ahead market bidding and bilateral contracts decomposition

Qian Cheng et al.

Summary: The complementary operation of hydropower, wind, and photovoltaic power is a cost-efficient solution for integrating intermittent wind and PV power. This study establishes a stochastic scheduling model to optimize the day-ahead market bids and the decomposition of daily contracts, aiming to maximize the profits and resource utilization efficiency of a wind-solar-hydro complementary system. The results show that the proposed model effectively decomposes the total energy of the daily contracts and achieves larger benefits, less power curtailment, and higher water resources utilization efficiency.
