A Novel Grid Interface, Optimized for Utility-Scale Applications of Photovoltaic, Wind-Electric and Fuel-cell Systems

9503176莫汉公用事业公司-正在计划在足够大的功率水平上使用光伏、风电和燃料电池系统。这种系统的技术和经济可行性在一定程度上取决于其电网接口的可靠性、安全性、成本和效率。提出了一种在公用事业规模的应用中利用系统条件的新型接口。提出了几项研究任务，通过7.5kW的实验室硬件样机来验证其性能。拟议接口的成功可能是朝着公用事业互动光伏、风电和燃料电池系统的可行性迈出的重要一步。由于提议的拓扑结构是完全新颖的，新的发现是完全可能的，这也将有益于提议的实用接口以外的系统。***

9503176 Mohan Utility-interactive photovoltaic, wind-electric and fuel- cell systems are being planned at sufficiently large power levels. The technical and economic feasibility of such systems partially depends on the reliability, safety, cost, and the efficiency of their grid interface. A novel interface, which takes advantage of the system conditions in a utility-scale application is proposed. Several research tasks are proposed to demonstrate and verify its performance by means of a 7.5 kW laboratory hardware prototype. The success of the proposed interface can be a significant step towards the feasibility of utility-interactive PV, wind-electric and fuel-cell systems. Because the proposed topology is completely novel, new discoveries are entirely possible which will also be beneficial to systems other than the proposed utility interface. ***
