Sustainable Electricity

The development of microgrids is of great interest to facilitate the integration of distributed generation in electricity networks, improving the sustainability of energy production. Microgrids in DC (DC-MG) provide advantages for the use of some types of renewable generation and energy storage systems, such as batteries. In this article, a possible practical implementation of an isolated DC-MG for residential use with a cooperative operation of the different nodes is proposed. The main criterion is to achieve a very simple design with only primary control in a residential area. This application achieves a simple system, with low implementation costs, in which each user has autonomy but benefits from the support of the other users connected to the microgrid, which improves its reliability. The description of the elements necessary to create this cooperative system is one of the contributions of the work. Another important contribution is the analysis of the operation of the microgrid as a whole, where each node can be, arbitrarily, a consumer or an energy generator. The proposed structures could promote the use of small distributed generation and energy storage systems as the basis for a new paradigm of a more sustainable electricity grid of the future.

Sustainable Electricity

We are used to the continuous supply of electricity from a socket. Behind the socket lies a complex system of large power stations, high-voltage cables, transformers and a distribution network. Little has changed in the system over the last fifty years. The ambition to generate sustainable electricity from variable solar and wind energy has an immense impact on the electricity sector and requires major changes in our electricity grid and its operation.

Iad Framework

This paper analyses the implementation of renewable off-grid technologies in rural areas, especially where an extension to the national electricity grid was not considered economically feasible. Implementation of remote, stand-alone, electricity technologies as alternatives to a grid connection to provide sustainable electricity access have often failed with many planned projects not realised or abandoned. Our initial assumption was that stand-alone electricity project exhibiting higher scores on sustainability indicators would benefit communities more and make their endurance more likely. However, the impact of the stand-alone technology was often overruled or its quality weakened by government preferences wishing to realise a connection to the central electricity grid. Empirically, the study compares three cases of stand-alone micro-hydropower projects and three cases of stand-alone solar photovoltaic projects in Bogor Regency, Indonesia. It is based on qualitative document analysis, complemented by multiple rounds of semi-structured interviews and observations. The paper assesses the extent to which each project met indicators of technical, economic, social, environmental, and institutional sustainability. The paper tries to explain the endurance of the project from these sustainability scores and uses additional explanations from Ostrom’s Institutional Analysis and Development (IAD) framework. The findings show that, for the studied local communities, the attractiveness of a grid connection overrules the virtues of a stand-alone electricity project, despite its quality, successful operation and impact. Our research also shows that government policy priorities changed in the rural electrification programme for some communities. In these situations, the off-grid rural electrification programme predominantly provided only temporary access to sustainable electricity for remote local communities that remained waiting and hoping for a grid connection to connect them to fossil fuel-dominated electricity.

Promising Source

The rising demands for a sustainable energy system have stimulated global interests in renewable energy sources. Wind is the fastest growing and promising source of renewable power generation globally. The inclusion of wind power into the electric grid can severely impact the monetary cost, stability and quality of the grid network due to the erratic nature of wind. Power electronics technology can enable optimum performance of the wind power generation system, transferring suitable and applicable energy to the electricity grid. Power electronics can be used for smooth transfer of wind energy to electricity grid but the technology for wind turbines is influenced by the type of generator employed, the energy demand and the grid requirements. This paper investigates the constraints and standards of wind energy conversion technology and the enabling power electronic technology for integration to electricity grid.

Legal Barriers

Despite increasing political emphasis across the Middle East on the need to transition to lower carbon, efficient, and environmentally responsible energy systems and economies, legal innovations required to drive such transitions have not been given detailed analysis and consideration. This chapter develops a profile of law and governance innovations required to integrate and balance electricity generated from renewable energy sources (RES-E) with extant electricity grid structures in the Middle East, especially Gulf countries. It discusses the absence of renewable energy laws, the lack of legal frameworks on public–private partnerships, lack of robust pricing and financing, and lack of dedicated RES-E institutional framework. These are the main legal barriers that must be addressed if current national visions of a low-carbon transition across the Middle East are to move from mere political aspirations to realization.
