Description
Summary:A future power grid should allow all types of generation including renewable energy, e.g. wind power and photovoltaic (PV). Over recent years, it has been witnessed a fast-growing renewable energy development throughout the world. Japan also pushes toward the renewable energy development setting out a target of 6610 MW wind power and 53 GW PV by 2030. This large penetration of renewable energy could pose negative impacts on the system security due to the uncertain output characteristics. This paper presents a method suitable to examine such impacts of a large penetration of renewable energy on the system Total Transfer Capability (TTC). The uncertainty associated with the renewable energy output and other system parameters is fully taken into account by means of a probabilistic approach, Monte Carlo simulation, and risk-based TTC selection. Besides, this paper considers the steady-state voltage stability to ensure a sufficient margin away from the voltage collapse point. The validity of the proposed method is illustrated through a numerical simulation conducted on the modified IEEE 30-bus test system.
