Policy Question

Revamping the electricity infrastructure to allow for an increased usage of renewable energy sources is a matter of concern in many parts of the world. In Europe, a major policy question is how to move energy demand to periods with surplus of renewable energy in the grid. In this paper we follow prominent Danish and German delegates working towards realizing the intelligent electricity infrastructure commonly known as ‘smart grid’ envisioned to be a significant actor in the management of renewable energy. Starting out with a view on smart grid that recognizes it as a partially existing object, we attend to its gradual emergence by focusing on two models and a metaphor evoked to represent smart grid development. As we contrast and compare these representational objects, smart grid emerges as a potential ‘thing’. Following Latour a ‘thing’ is a gathering of many actors agreeing and disagreeing about what the thing ‘is’ (its ontological status). In the paper we show how smart grid innovation both emerges – and fails to emerge – as an object of relevance to a broader public. Even though users play an important role in the imagination of experts, a gap remains between the experts and those who smart electricity infrastructures will come to affect. Concerned with this gap we argue that Science and Technology Studies must pay attention to how smart grid development gets constructed as a public problem in specific imaginative spaces of opportunity and closure.

Surplus Power

Energy demand is growing at a very rapid pace worldwide. Conventional energy sources are being replaced steadily by non-conventional sources such as renewable energy sources like wind, solar, geothermal, hydroelectric etc. This rapid growth in demand for energy compounded by the depletion of conventional, non-renewable energy sources in recent years has brought about a transformation in the energy sector. Households, manufacturers and other consumers of energy can now both produce and consume energy. The flow of energy is bidirectional. They can also either store the surplus power for future use or send it to the grid for sharing with other users of energy. As a result of this transformation, the smart grid came into existence where the producers and the consumers of energy can be the same person and contribute to the supply of energy to the grid.

The increase in population and industrialization has increased the consumption of electricity. Currently, it is impossible to live without electricity. Indeed, it is necessary for the economic, social and industrial progress in all the countries of the world. This is why we are always asked to develop all types of energy to produce clean and safe to improve energy efficiency. Indeed, the use of new renewable energy sources helps to mitigate greenhouse gas emissions and dependence on centralized energy sickles. The difficulties of renewable energy-based power systems lie in their production, which is not controllable and may not meet the increase in energy demand.

Finding techniques to meet the growing power demand is the greatest challenge for industrialists, engineers and entrepreneurs of the country. Wind energy is emerging as one of the various renewable energy sources, which contributes to the appreciable energy demand in the world. This paper focuses on the fabrication of multirotor windmill, which has two sets of turbine blades, out of which, one set of blades rotates in the clockwise direction and the other set in the anticlockwise direction. Conventional method is used for the design of blades. The floor space required for both the windmills are same. The two sets of blades are coupled by a Bevel gear mechanism which in turn, produces a uniform torque. When compared to the normal windmill, the proposed windmill has higher efficiency due to the presence of second set of blades.

Day by day the non-renewable sources of power are getting depleted. Due to higher demands of energy the necessity of such sources is becoming more important in the field of electrical power according to the estimates of power sector the usage of renewable component has increased by 9% w.r.t to 2013. Even though non-renewable sources capacity increasing day by day the complexity of the power system network increasing which result in mismatch between voltage and power in electrical network. By using smart grid technology, we can minimize the unequal effect of voltage and power in the domain of renewable energy source. Smart grid technology uses digital transformation of electrical parameter to central coordination center at high sample rate, which uses effective and reliable operation in managing energy demand of renewable energy sources

Due to the rapid increase in energy demand with depleting conventional sources, the world’s interest is moving towards renewable energy sources. Microgrid provides easy and reliable integration of distributed generation (DG) units based on renewable energy sources to the grid. The DG’s are usually integrated to microgrid through inverters. For a reliable operation of microgrid, it must have to operate in grid connected as well as isolated mode. Due to sudden mode change, performance of the DG inverter system will be compromised. Design and simulation of an optimized microgrid model in MATLAB/Simulink is presented in this work. The goal of the designed model is to integrate the inverter-interfaced DG’s to the microgrid in an efficient manner. The IEEE 13 bus test feeder has been converted to a microgrid by integration of DG’s including diesel engine generator, photovoltaic (PV) block and battery. The main feature of the designed MG model is its optimization in both operated modes to ensure the high reliability. For reliable interconnection of designed MG model to the power grid, a control scheme for DG inverter system based on PI controllers and DQ-PLL (phase-locked loop) has been designed. This designed scheme provides constant voltage in isolated mode and constant currents in grid connected mode. For power quality improvement, the regulation of harmonic current insertion has been performed using LCL filter. The performance of the designed MG model has been evaluated from the simulation results in MATLAB/ Simulink.

Several Western Balkan states face the consequences of the Yugoslavian war, which left hometowns with dilapidated electricity grid connections, a high average age of power plant capacities and low integration of renewable energy sources, grid bottlenecks and a lack of competition. In order to supply all households with electricity, UNDP Croatia did a research on decentralized supply systems based on renewable energy sources. Decentralized supply systems offer cheaper electricity connections and provide faster support to rural development. This paper proposes a developed methodology to financially compare isolated grid solutions that primarily use renewable energies to an extension of the public electricity network to small regions in Croatia. Isolated grid supply proves to be very often a preferable option. Furthermore, it points out the lack of a reliable evaluation of non-monetizable aspects and promotes a new interdisciplinary approach.

The article is aimed at developing strategic directions and introducing regulatory measures for the formation of Ukraine’s energy policy on the principles of energy saving and the development of renewable energy industry. On the basis of scientific works, the main organizational-economic vectors of energy industry sector development are systematized, which are associated with the formation of a favorable socio-political climate regarding the priority of using renewable energy sources in the fuel and energy complex; development of effective methods of both the State-based and the market-based regulation by the world community; coordination of the strategy of sustainable development of the world economy. It is determined that the energy saving policy should be based on a flexible combination of the State-based regulation and the market environment for the formation of the most acceptable stimulation mechanisms in the specific economic and political situations, which allows for the greatest economic benefit. It has been found out that the implementation of energy saving processes is impossible without the mass use of renewable energy carriers, which are a universal resource for processing to the right types of energy, are marked by energy independence related to obtaining economic benefits and contribute to the creation of an ecological friendly environment. In the perspective, the energy saving processes, the transition of the national economy to wide implementation in the production of high-tech technologies and the use of renewable energy sources should become the determining factors of Ukraine’s energy strategy.
