Low Efficiency

An increase in the share of renewable energy sources characterized by intermittent generation leads to a decrease in the quality of electricity and the need to balance the load on the network. The methods used today for balancing the load on the generation side, as well as the use of energy storage technology, do not always provide an effective solution to the balancing problem. This is especially evident when traditional generators are transferred from the base load electricity sources to the reserve ones. The main issue is the increased electric energy losses due to the low efficiency of the power storage technology. Using the most advanced hybrid power plant Gorona del Viento (El Hierro island, Canary archipelago, Spain), which includes traditional and renewable energy sources, as reference, we are describing the methods of balancing the load on the network, which includes balancing, both the electricity generation and consumption. Using the calculation models of the hybrid power plant operating modes, the possibility of implementing various load balancing strategies on the consumption side has been demonstrated, their features have been analyzed, their effectiveness in reducing energy losses has been demonstrated.

Abstract The problem of global warming is a problem facing the world community. Since the Industrial Revolution’s birth, the use of energy from fuel oil (FF) has surged, and this causes an increase in Greenhouse Gases (GHGs) resulting from burning fuel. This GHG is the cause of the rise in the earth’s temperature, which is estimated to one day, the earth is not comfortable and even no longer habitable. The solution to the problem is reducing GHGs that can be done by saving fuel use, which is replaced with renewable energy sources (REs). RE sources are obtained from the Solar Power Plant (SPP), Wind Energy Power Plant (WEPP), Ocean Wave and Current Power Plant (OWPP and OCPP), Nuclear Power Plant (NPP), Biodiversification Power Plant (BPP), Hybrid Power Plant. Besides, REs can also increase the overall electrification in Indonesia, such as in East Nusa Tenggara. However, the electrification rate is still low in quality. According to the Republic of Indonesia Government Regulation 2014, the National Energy Policy mandates that energy mix from REs in 2025 is expected to reach 23%. This paper presents a literature review on new and renewable energy that can be considered early in their use.

Hybrid Power Plant

Stand-alone hybrid power plants based on renewable energy sources are becoming a more and more interesting alternative. However, their management is a complex task because there are many variables, requirements and restrictions as well as a wide variety of possible scenarios. Though a proper sizing of the power plant is necessary to obtain a competitive cost of the energy, smart management is key to guarantee the power supply at a minimum cost. In this work, a novel hybrid power plant control strategy is designed, implemented and simulated under a wide variety of scenarios. Thereby, the proposed control algorithm aims to achieve maximum integration of renewable energy, reducing the usage of non-renewable generators as much as possible and guaranteeing the stability of the microgrid. Different scenarios and case studies have been analyzed by dynamic simulation to verify the proper operation of the power plant controller. The main novelties of this work are: (i) the stand-alone hybrid power plant management regarding a battery energy storage system as a part of the spinning reserve, (ii) the characterization of the largest loads as non-priority loads, (iii) the minimization of the needed spinning reserve and fuel consumption from diesel generators.

This article deals with the analysis of a day-ahead generation diagram in specific part of a power network with renewable energy sources. As a renewable energy source a photovoltaic power plant was chosen. Input data for a day-ahead analysis was obtained from the database of previous measurement that was realised on the existing configuration in off-grid network at the department of authors. The simulation network was created in Matlab/Simscape Power System environment that consisted of rotating generators (for regulation of generated power due to fluctuated power generation from photovoltaic sources) and photovoltaic power plant of variable energy generation and loads. The results refer to a necessity to consider the previous measured data of the weather for prediction of future expectation of a day-ahead load diagram.

Design Study

Design study of a synergetic system among small long life gas cooled fast reactors and renewable energy has been performed. A pump storage system is the center in the integration among considered energy sources. Using this system many renewable energy sources and the small nuclear power plant can be integrated to produce reliable energy sources which can be used for electricity production, desalination, etc. In this system each energy source can store energy by contributing pumping water from a low level reservoir to a high level reservoir. The nuclear power plant module must satisfy inherent safety requirement, and have flexibility in producing electricity, clean water (through desalination), etc. The reactor can be operated for 25 years without the necessity to refuel during that period. To achieve inherent safety capability it is important to minimized excess reactivity during burn-up to be below delayed neutron fraction value so that super prompt critical accident such as in Chernobyl accident case can be avoided. Here minimization of excess reactivity is carried out by adjusting core and blanket region width and plutonium enrichment in core regions.
