Abstract

The invention discloses a short-term operation adequacy evaluation method for an energy interconnection system, which comprises the following steps: 1) establishing an evaluation index system for the operation adequacy of the energy interconnection system; 2) collecting data before the energy interconnection system; 4) Simulate the operation status of each component of the energy interconnection system; 5) Based on the timing characteristics of each system in the energy interconnection system, establish the coupling operation status of the energy interconnection system Simulation; 6) Using Monte Carlo simulation to evaluate the adequacy of the energy interconnection system in the operating state. The invention improves the accuracy by taking the average value of multiple simulations, and can reasonably evaluate the adequacy of the energy interconnection system in operation.

Description

technical field [0001] The invention belongs to the field of short-term operation system evaluation, and in particular relates to a short-term operation adequacy evaluation method of an energy interconnection system. Background technique [0002] The short-term evaluation of power system operation reliability is defined as: taking into account the health status of the equipment itself, external environmental conditions, system operating conditions and system operation behavior, the power system will continuously provide the power system with acceptable quality standards and required quantities in a short period of time. A measure of the ability of an electricity user to provide electricity and quantity. [0003] Traditional reliability assessment usually provides a decision-making basis for power system planning and design, mostly with medium and long-term indicators. There is a lack of research methods for the short-term operation adequacy of power systems containing varia...
