能量管理系统
摘要：
能量管理系统(1)具备与HVDC总线(10)连接的发电装置(20)、双向DC‑DC变换器(30)以及逆变器(40)。使双向DC‑DC变换器(30)和逆变器(40)各自的电压变化相对于电流变化的增益相等。在伴随着发电装置(20)的输出电流的变动而逆变器(40)或双向DC‑DC变换器(30)的输出电力变动了的情况下，能量管理系统(1)调整双向DC‑DC变换器(30)的增益特性相对于逆变器(40)的增益特性的偏移ΔV，使逆变器(40)的输出电力收敛于目标值。由此，提供一种能够通过简易的控制使逆变器的输出电力稳定化的能量管理系统。
摘要（英）：

This energy management system (1) is provided with a power generating device (20), a bidirectional DC-DC converter (30) and an inverter (40), which are connected to an HVDC bus (10). The bidirectional DC-DC converter (30) and the inverter (40) each have the same voltage change gain relative to a change in current. If the output power from the inverter (40) or the bidirectional DC-DC converter (30) varies concomitant with a variation in the output current from the power generating device (20), the energy management system (1) adjusts an offset delta V of the gain characteristic of the bidirectional DC-DC converter (30) relative to the gain characteristic of the inverter (40), and causes the output power from the inverter (40) to converge to a target value. In this way it is possible to provide an energy management system with which the output power of an inverter can be stabilized using simple control.
