The applications of battery energy storage systems (BESSs) in power systems have been paid increasing attention in recent years. Apart from all the benefits that BESSs can bring to the power systems, their potential applications in assisting power system restoration after a major blackout have not yet been systematically investigated. The flexible charging and discharging characteristics of BESSs...
A stochastic optimization approach is proposed for the unit commitment problem with the uncertainty of wind power generation taken into account, based on mixed-integer linear programming (MILP). The problem is formulated to minimize the total operation cost of thermal units. In considering wind power generation, scenarios are generated by Latin hypercube sampling (LHS) and the stochastic optimization...
The prerequisite for stable system frequency is to have instantaneous balance of demand and generation of active power. In the framework of the well-known mechanism design theory, the problem of designing an optimal contract between a utility company and a pumped-storage power plant is investigated for frequency regulation that could act as an effective tool for system frequency control in deregulated...
As power system restoration (PSR) is a multi-variable, multi-objective, and multi-constrained nonlinear optimization problem, it is difficult to establish a well-defined mathematical model to reasonably describe it. Given this background, a new distributed model for PSR is proposed in this paper by combining multi-agent technology (MAT) with tabu search method (TSM). The proposed model consists of...
