Coordination of system planning and operation using probabilistic risk assessment method

Reliable operation of a power system depends on sound operating strategies and insightful system planning. Exceeding investment on a system results in high reliability level and high cost. An insightful system planning should consider the system planning and operation coherently. In this paper, a general framework on coordination of system planning and operation is proposed. Based on the risks of events, a hierarchical structure with three zones is proposed to identify the boundary of planning and operation. The impacts of events can be measured by risk indices. Some potential risk measurement methods that can be integrated into the proposed framework are discussed. The propose method is demonstrated on a modified IEEE 30-bus system.
