电力系统通常在严格的频率范围内运行。当电力系统负载发生变化时，电力系统频率将以最初由电力系统惯性确定的速率变化。因此，电力系统惯性是电力系统的重要组成部分，因为它决定了系统频率对供需不平衡的敏感性。随着可再生能源发电系统被添加到电力系统中，重要的是评估其对整个系统惯性的影响。这对于相互联系很少的小岛屿系统尤其重要。在这方面有两个重要的考虑因素，即发电系统的存储动能和发电系统提供或吸收当负载发生变化时将发生的能量不平衡的能力。影响这一点的因素是发电系统的物理组成和所用发电机的类型。本文探讨这些因素都为风力涡轮机和潮汐能装置
Power systems are usually operated within strict frequency ranges. When there is a change in the power system load the power system frequency will change at a rate initially determined by the inertia of the power system. Power system inertia is therefore an important component of a power system as it determines the sensitivity of the system frequency to supply demand imbalances. As renewable energy generation systems are added to power systems, it is important to assess their impact on overall system inertia. This is especially important for small island systems with little interconnection. There are two important considerations in this regard namely the stored kinetic energy of the generation system and the ability of the generation system to provide or absorb the energy imbalance that will occur when a change in load occurs. The factors that affect this are both the physical make up of the generation system and the type of electrical generator employed. This paper examines these factors both for wind turbines and tidal energy devices
