This paper presents an application of the stochastic optimal power flow method to determine the energy and reserve schedules for a system with large amount of wind generation. Unlike contingency analysis, the requirements for operating reserves based on the stochastic optimal power flow are not predefined. Instead, the reserve requirement is generated to meet both the system reliability and economic efficiency under system uncertainties.Wind generation is modeled as an uncertain power injection in the stochastic optimal power flow problem. The case study on the WSCC-179 bus system with a large uncertain wind resource in the Tehachapi area shows the impact of intermittent generation on the reserve requirement, and so identifies and addresses emerging system issues regarding the installation of large-scale wind generation. A comparison of the reserve procurement for different levels of wind generation shows the necessity of adequate reserve for system with large wind generation.

The stochastic OPF methodology can be used to determine system operating reserve requirements, because operating reserve is intended to support system operation following a contingency.…”

This paper presents a methodology to determine the energy and reserve schedules with consideration of power system uncertainties. Unlike contingency analysis, the requirements of operating reserves based on the stochastic optimal power flow are not predefined. Instead, the reserve requirement is generated to meet both the system reliability and economic efficiency under system uncertainties. The stochastic optimal power flow with reserve determination is proposed and studied with different types of uncertainties, including variation of system demand, outages of transmission lines and generation units, and intermittent generation. This study emphasizes the impact of the intermittent generation on the energy schedule and reserve determination, and so provides a new methodology for addressing emerging system issues with the emergence of renewable energy. Exploring a variety of cases reveals the differences between contingency analysis and risk-based motivations for reserve.
