This paper discusses the development of multi-document summarization for Indonesian documents by using hybrid abstractive-extractive summarization approach. Multi-document summarization is a technology that able to summarize multiple documents and present them in one summary. The method used in this research, hybrid abstractive-extractive summarization technique, is a summarization technique that...
This letter presents a new method, the fast -iteration method, to solve the economic dispatch (ED) problem considering the prohibited operating zones (POZs) and ramp rate limits of generation units. Necessary conditions for the optimal solution of the ED problem are presented and proved. The efficiency of the method has been verified on a 15-unit system and a Korea...
This paper briefly discusses a motivation of the Faculty of Electrical Engineering at the Czech Technical University in Prague (FEE CTU) for founding the Business Process Center of Excellence. It is mainly focused on a description of a business process management (BPM) implementation at FEE CTU, proofs of success and best practices or experience gained during the project. Attention is paid particularly...
Modern commercial operations consist of critical equipments that are more susceptible to voltage sag events. The consistent and smooth running of these operations is often disrupted by voltage sags. Diverse range of solutions exist which can enhance the ride through capability of sensitive devices. This paper presents various voltage dip mitigation solutions and a methodology for analyzing the effectiveness...
Energy storage systems that are properly placed on the transmission system can be used to relieve transmission congestion [1]. Similarly, storage on distribution can be used to reduce peak loads [2]. The reduction in currents produced by congestion relief and peak reduction may also result in a decrease in line losses. Further efficiency improvements could be realized by optimizing the placement and...
This paper establishes an economic operation model of microgrid including photovoltaic, wind energy, heat recovery boiler and battery. The emission of pollutant and greenhouse gases is taken into account and the minimum operation cost of microgrid is taken as objective function. The proposed model is solved by particle swarm optimization algorithm. Besides, the feature of battery is also studied,...
In the current power market environment of China, lease operation mode of pumped storage power station is an efficient way to realize static and dynamic benefits of power station, also it's one of main operation mode in China. A two-party profit model among pumped-storage power station and grid companies was build. The profits of power station and grid company were discussed to meet the individual...
Based on the background of multi-rope friction hoisting transport system and the factual loading of hoisting skip as the object monitored, a practical and economic monitoring system scheme has been put forward, which is not only capable of monitoring the factual loading of hoisting skip but also can detect the quantity of unloaded coal left in hoisting skip after the process of unloading expediently,...
Sustainability is one of the global grand challenges of the 21st century. In order for future generations to enjoy a satisfactory quality of life, the current generation must find ways to meet humanity's needs for energy, shelter, food and water in ways that are environmentally, economically, and socially sustainable. Engineers must be trained to design systems and technologies that have a small environmental...
