The Stability

The crises linked to the high costs of oil and environmental pollution have led to think about the large-scale use of systems that use renewable energy sources, as a measure to mitigate these impacts. In Cuba there are more than 10,000 installations that take advantage of renewable sources using different technologies, these are of small format; but also there are conditions of a renewable potential distributed throughout the national territory, which allows us to continue introducing these practices in a larger scale and format. The work deals, with the possibilities offered by the use of the potential of the renewable energy source as a measure of economic savings and reduction of disaster risks, exposing the need to link the facilities that take advantage of these resources, with the stability of the energy services for the confrontation of natural disasters and for exceptional situations, in addition to the rescue of certain energetic cultural traditions, which can help in the formation of social habits of efficiency and austerity in consumption, propitiating the reduction of the associated environmental impacts and the promulgation of a legal norm that protects and orders the penetration of renewable sources in the national energy matrix.

Stability Issues

In recent years, many applications have been developed for the integration of renewable energy sources (RES) into the grid in order to satisfy the demand requirement of a clean and reliable electricity generation. Increasing the number of RES creates uncertainty in load and power supply generation, which also presents an additional strain on the system. These uncertainties will affect the voltage and frequency variation, stability, protection, and safety issues at fault levels. RES present non-linear characteristics, which requires effective coordination control methods. This paper presents the stability issues and solutions associated with the integration of RES within the grid.

Utility Grid

In India, Electrical Power System is adapted to handle both constant loads and variable loads, also power is generated in two types; one is due to fossil fuels, and another one is due to renewable energy sources. However, renewable energy sources are playing a vital role in the production of clean energy and also useful for the reduction in greenhouse emission. Nevertheless, when there is any additional change in the generation side concerning to input supply, which is due to the uncertainty of nature, can create new challenges for the system operators and utility centers. It is not an easy task for the utility centres and supply operators to integrate variable renewable energy sources with the utility grid. This paper explores an overview of some operational techniques and solutions, which are helpful for high penetration of renewable energy sources such as solar and wind energy. It also explores operation, control management and challenges due to renewable energy when they integrated with the utility grid. By interfacing of renewable energy sources with a utility grid with proper management and control can provide bi-directional communication between suppliers and consumers smartly. The aim of integrating large scale renewable sources from transmission and distribution network into an existing system is to reduce the power quality issues, demand response, forecasting, peak demand, and improve network security, fast scheduling and dispatch, aiming towards smart grid technology for electrical power systems.

The authors review the development of unconventional power generation units in Germany in the last 10 years with a view to possible scenarios in 2035 and 2040. The dynamic development of production from renewable energy sources led to the fact that in some parts of Germany the plan for the production of electricity from renewable sources for 2025 was reached in 2011. Bearing in mind that about 97% of all renewable energy production units are connected to distribution networks, the question of operational production management arises. The paper presents technical solutions for the management of production from renewable sources, as well as the necessary technical requirements for the connection of generator units that are connected to the grid via inverters in order to preserve the stability of the power system.

Lighting Retrofit

The use of formal methods and artificial intelligence has made it possible to automatically design outdoor lighting. Quick design for large cities, in a matter of hours instead of weeks, and analysis of various optimization criteria enables to save energy and tune profit stream from lighting retrofit. Since outdoor lighting is of a large scale, having luminaires on every street in urban areas, and since it needs to be retrofitted every 10 to 15 years, choosing proper parameters and light sources leads to significant energy savings. This paper presents the concept and calculations of Levelized Cost of Electricity for outdoor lighting retrofit. It is understood as cost of energy savings, it is in the range from 23.06 to 54.64 EUR/MWh, based on real-world cases. This makes street and road lighting modernization process the best green “energy source” if compared with the 2018 Fraunhofer Institute cost of electricity renewable energy technologies ranking. This indicates that investment in lighting retrofit is more economically and ecologically viable than investment in new renewable energy sources.

Cross Border

The energy transition in Europe requires not only the implementation of technological innovations to reduce carbon emissions but also the decentralised extension of these innovations throughout the continent, as demonstrated by the ‘Clean Energy for All Europeans’ package. However, decentralised energy generation, and specifically electricity generation, as it gives rise to new players and interactions, also requires a review of the energy planning process. In this sense, governance becomes the key concept for understanding the implementation of the energy transition in a territory. This is particularly visible in a cross-border setting, especially considering cross-border cooperation in the development of renewable energy sources (RES) provides the necessary elements to determine the criteria of local regulation between the different levels of governance. In light of the current legal framework in France, this paper presents the institutional framework of the multi-level governance of the RES development planning process. It concludes that it is quite conceivable for the rationales of governance at the local level (decentralisation) and the large-scale operation of a large interconnected network (Europeanisation) to coexist.
