This paper presents a modified formulation for the wind-battery-thermal unit commitment problem that combines battery energy storage systems with thermal units to compensate for the power dispatch gap caused by the intermittency of wind power generation. The uncertainty of wind power is described by a chance constraint to escape the probabilistic infeasibility generated by classical approximations of wind power. Furthermore, a mixed-integer linear programming algorithm was applied to solve the unit commitment problem. The uncertainty of wind power was classified as a sub-problem and separately computed from the master problem of the mixed-integer linear programming. The master problem tracked and minimized the overall operation cost of the entire model. To ensure a feasible and efficient solution, the formulation of the wind-battery-thermal unit commitment problem was designed to gather all system operating constraints. The solution to the optimization problem was procured on a personal computer using a general algebraic modeling system. To assess the performance of the proposed model, a simulation study based on the ten-unit power system test was applied. The effects of battery energy storage and wind power were deeply explored and investigated throughout various case studies.

With the rapid development of wind power, electric grid faces significant challenges from the variable nature and anti-peak-regulation characteristic of wind power. In order to mitigate the impact of wind power, large capacity electrochemical energy storage is proposed to solve this problem. This study establishes a unit commitment (UC) model with large capacity electrochemical energy storage given the specific characteristics. Meanwhile, wind forecast deviation and curtailment are considered. Case studies with modified IEEE 39-bus system are employed to validate the proposed method. The impact of electrochemical energy storage system on economics, peak load shifting and accommodating wind power is analyzed.
