Purpose of review In the past decade, China has made remarkable achievements in the development of renewable energies. This article adopts a geographical perspective for China’s current wave of renewable energy transitions, by viewing the transition outcomes through the lenses of spatial clustering and socio-spatial embeddedness. Recent findings We find that many renewable energy industry clust...

Large-scale deployment of renewables in island energy systems attracts local attention of grid operators as a way of reducing fuel fossil consumption. Planning a grid based on renewable power plants poses serious challenges to the normal operation of a power system, namely on frequency and voltage stability. In past grid code compliance, wind turbines did not require services for supporting gri...

geothermal investors need to be confident with the methods and results of exploration programs. also cutting the upfront cost of geothermal exploration will further encourage investors to consider investment in this emerging clean energy field. hence, it is of paramount importance to improve prospecting techniques in order to explore where economic concentrations of geothermal energy are to be ...

the renewable energy sources and plug-in electric vehicles (pevs) are becoming very popular because of the combination of high fuel costs and concerns about emission issues. this paper presents modelling and control of a building integrated fuel cell and plug-in electric vehicles (bifc-pev) in smart distribution systems. in bifc-pev system, conventional building elements could be replaced by sp...

Conventional power systems have been planned with dispatchable generation using deterministic planning and operating methods and tools since the inception of the industry, with little exception. It now appears that the future power system will need to successfully integrate a high share of non-dispatchable renewable energy whose production exhibits much greater variability and uncertainty than ...

Sustainability has gained tremendous importance and has been an important issue both for policy makers and practitioners. Realizing that the resources on the earth are limited, renewable energy alternatives have flourished and started to replace the conventional energy alternatives. Energy planning using different energy alternatives, for the long term becomes a vital decision. In this study, f...

This paper considers the problem of strategic planning of energy grids where the power demands are served from renewable energy sources, such as wind farms, and the transmission network is represented by High-Voltage Direct Current (HVDC) lines. The principal question considered in this work is whether a risk-averse design of the grid, including the selection of wind farm locations and assignme...

Renewable energy sources today can provide a promising alternative to conventional power generation, provided some economic, institutional, social and technical barriers could be overcome, and the appropriate planning instruments for their deployment are developed. In Greece, contemporary practice seems inadequate to address the multiple character of renewables and the need to ‘open up’ the dec...

the use of renewable energy in power generation and sudden changes in load and fault in power transmission lines  may cause a voltage drop in the system and challenge the reliability of the system. one way to compensate the changing nature of renewable energies in the short term without the need to disconnect loads or turn on other plants, is the use of renewable energy storage. the use of ener...
