This paper presents studies on improving the robustness of shipboard dc hybrid power systems. The shipboard power system can be regarded as an islanded microgrid. The objective, in particular, is to reduce the load curtailment when generator failures take place in the islanded microgrid. By applying the basic unit commitment (UC) operation model, the loads can be fully supplied during normal condition...
Careful design and planning is essential for successful integration of energy storage system (ESS) in a shipboard dc hybrid power system. An optimization model for resiliency enhancement and total cost reduction is proposed in this paper. The resilience of a shipboard power system with and without ESS are evaluated by means of resiliency index values under fault conditions. Furthermore, the influence...
In this paper, a comprehensive protection strategy is proposed for insuring dependable and secure operation of an islanded microgrid system. This is implemented using microprocessor-based relays to prevent unnecessary loss of critical loads and distributed generators (DGs). Several improvements are proposed to clear the way for plug-and-play of DGs. Furthermore, recommendations are presented to tackle...

This is implemented using microprocessor based relays to prevent unnecessary loss of critical loads and distributed generators (DGs). Several improvements are proposed to clear the way for plug-and-play of distributed generators (DGs) and loads. Furthermore,...
The short-term photovoltaic power generation forecasting is of great significance for the power system and energy management system(EMS). In this paper, the short-term forecasting model of PV generation power based on the RBF neural network is proposed, which forecast the power of PV generation system for the next 24 hours. Factors of position, environment, and inner performance of the system are...
