Development Perspective

Energy transition has become a priority for adaptive policy and measures taken in response to climate change around the world. This is an opportunity and a challenge for the Taiwan government to establish a climate-resilient power generation mixed to ensure electricity security as well as climate change mitigation. This study adopted a sustainable development perspective and applied optimal control theory to establish a cost-effective model to evaluate a long-term (2050), climate-resilient power generation mix for Taiwan. Furthermore, this study applies the STIRPAT approach to predict the demand of electricity by 2050 for the demand side management. The results not only showed the share of various power generation mixed, but also recommended the trajectory of electricity saving by 2050.

The development of integrated gasification combined cycle (IGCC) systems provides cost-effective and environmentally sound options for meeting future coal-utilizing power generation needs in the world. The combustion of gasified coal fuel significantly influences overall performance of IGCC power generation. Experimental measurements are carried out on a non-premixed model combustor, equipped with a double-swirled syngas burner. Planar laser-induced fluorescence (PLIF) of OH radical measurement is adopted to identify main reaction zones and burnt gas regions as well. Together with the temperature and emission measurements during the exhaust section, some important characteristics of the syngas flame are investigated overall. In this paper, the effects of the CO/H2 molar ratio consisting of syngas fuel are investigated under different humidity. With the increase of CO/H2 ratios, the concentration field of OH radicals is gradually away from the nozzle exit, and the nozzle exit almost no existence of OH radicals, forming a typical lifted flame. In addition, fluorescent signal strength of OH radicals pronounced weakening, the flame gradually appeared W type distribution and more and more obvious with the increased of humidification amount. At the same time the average exhaust temperature of combustor CO and NOx missions almost no change. The study can provide a reliable database for high moisture gas turbine combustor design and combustion numerical simulation.

Successful development of a marine wave energy converter (WEC) relies strongly on the development of the power generation device, which needs to be efficient and cost-effective. An innovative multi-input approach based on the Convolutional Neural Network (CNN) is investigated to predict the power generation of a WEC system using a double-buoy oscillating body device (OBD). The results from the experimental data show that the proposed multi-input CNN performs much better at predicting results compared with the conventional artificial network and regression models. Through the power generation analysis of this double-buoy OBD, it shows that the power output has a positive correlation with the wave height when it is higher than 0.2 m, which becomes even stronger if the wave height is higher than 0.6 m. Furthermore, the proposed approach associated with the CNN algorithm in this study can potentially detect the changes that could be due to presence of anomalies and therefore be used for condition monitoring and fault diagnosis of marine energy converters. The results are also able to facilitate controlling of the electricity balance among energy conversion, wave power produced and storage.

Renewable Hydrogen

Hydrogen is likely to play a significant role in the concept of low-carbon power generation in support to renewable energy systems. It is abundant, eco-friendly, highly efficient and have the potential to be more cost-effective than fossil fuels provided that the engineering challenges associated with its safe infrastructure development, economical extraction and storage are solved. Presently, about 50 million metric tons of hydrogen is generated on a yearly basis, most of that is used for oil refining and ammoniac production. Other applications include electric vehicles, power to gas and power generation, etc. This study focuses on the use of hydrogen for power generation. The main goal is to investigate technical and economic performances of a renewable hydrogen-based energy system as an alternative to diesel generators for powering a remote telecoms base station. The proposed energy system consists of a photovoltaic generator, an electrolyser, a fuel cell, a hydrogen tank, a battery storage system and a power-conditioning unit. The system is simulated using Homer Pro software.

The Impact

The current coal-fired power generation market requires higher cycle efficiencies not only for economic reasons, but also as a means of reducing plant carbon footprint. To achieve these goals, the plant must operate at higher pressures and temperatures in the supercritical (SC) and ultrasupercritical (USC) domains. This paper describes Bechtel’s experience and challenges in regard to the conceptual design and integration of large steam turbines operating under these severe conditions. Several examples of projects are described wherein Bechtel applied this neutral but proactive technical approach in the development or design phase to achieve the best and most cost-effective solution for its customers. The topics presented also relate to steam cycle optimization in terms of plant output, steam conditions, number of reheat circuits, and type and number of heaters. The impact on balance of plant systems, including water treatment, availability, and redundancy criteria, is also addressed.

The U.S

Natural-gas-fired combined cycle plants have become the preferred technology for new power generation because of their high thermal efficiency and superior environmental characteristics. An outcome of the recent resurgence in the U.S. power market is that the average size of the new power plant has increased, leading to the use of two or three advanced gas turbines (GTs) per plant. In lieu of the traditional multishaft arrangement, some GT suppliers are advocating the use of multiple trains of their single-shaft reference plants. This paper covers salient differences between the two approaches and discusses at length the major variables and their impact on balance-of-plant cost that must be carefully examined for a cost-effective solution.

At present, China has built a number of DG (distributed power generation) demonstration projects as part of intelligent cities, intelligent business parks, university campuses and residential areas. The interaction mechanism, among DGs-especially those with energy storage, the users and the distribution grid need to be clear; i.e. how to unify the coordination among solar power systems, small wind power generation systems, the battery energy reserve systems, and electrical vehicles, so as to optimize resources allocation, cut peak and compensate trough loads; how to enable future homes and business users has more flexibility, controllability on electricity usage thus to advance the technology development in the field of electricity usage. The above mentioned problems can be solved smoothly by researching on the comprehensive use of modern power electronic technologies, communication technologies, computer and network technologies, advanced sensor and measurement & control technology, to combine them together for monitoring, protection control, cloud computing , and management of power supply department for active distribution network after DG access, to constitute the comprehensive dispatching system based on the DG of cloud computing. Dispatching of DG for distance dispersion location and a huge number of terms, to based on the cloud computing is very cost-effective, and it is worthy of further study and application.
