The Cost

The energy from renewable sources had always been perceived as free or at least lower-cost energy, with its sourcing from natural sources such as solar radiation and wind energy. In actual the cost breakdown of renewable energy would exceed that of traditional energy sources in almost all cases. This study attempts to produce a cost model for renewable energy systems. The model takes into account different requirements and site variations into account. In this paper, elements of the cost model Renewable Energy System (RES) especially, photo-voltaic solar systems, have been investigated. Cost items are presented alongside a to-do checklist for the new Photo-Voltaic (PV) solar energy system. The goal of this study is to construct a model that would cover the cost sources as well as bring to attention the unexpected sources of cost variations that include all possible cost items of a new solar renewable energy system. The feasibility of the new system is expressed in terms of Total Cost (T.C) and Cost of Energy (COE). The model can evaluate the feasibility of off-grid as well as on-grid systems. The model investigated properly as well as an empirical analysis and verified through results comparison with reviewed case studies. The results revealed that the cost of off-grid systems is higher than the cost of on-grid systems due to the cost of batteries as well as the cost of standby generators. So, it would be more feasible to use an off-grid system only in remote or isolated areas. Risk Cost lists, ranking and success factors of new renewable projects are exhibited.

The main goal of this work is to find economical alternative energy supply solution for poultry industry in Egypt. By studying the economic feasibility of using hybrid renewable energy resources as main source of power for existing poultry farm in Egypt to reduce existing operational cost of energy and add resilience and reliability dimensions for the operation of poultry farm in rural locations. In addition to reducing the environmental impact of using poultry litter in its fundamental form. This hybrid system connected to grid is used in the company to avoid instability problem in which the company suffered when they applied biomass energy source as main power source to their farm in Lebanon. The grid will be used as energy storage during the excess energy production form the hybrid system and to add some resilience and reliability dimensions to the hybrid system to prevent instability to the farm ‘s grid due to the high penetration of renewable energy. The economic feasibility is evaluated of this configuration using HOMER versus different configurations and sizes for these systems including the existing situation of depending only on grid as main source of energy. The results showed that the best configuration is 400 kW biomass generator, and 500 kW PV plant will satisfy the average demanded load of 9660 kWh daily with using the grid as backup energy source. The cost of energy for this configuration will be 0.0894 $/kWh which is lower than continuing existing situation depending on the grid as main source of power in which its Cost of Energy (COE) will reach during the lifetime of the project to 0.184 $/kWh due to the increase in COE in Egypt by 8%.

The Cost

Providing energy to areas isolated from the electricity grid through the use of a smart integrated renewable energy system (SIRES) is proposed in this study for Valparaiso, Chile. The study analyzes the process of identifying the appropriate size of a SIRES considering technical and economic factors. An optimization model proposed in the literature was modified, and a subsequent spatial–temporal analysis of the different variables was conducted. The model comprises locally available renewable energy resources, such as biomass, biogas, wind power, solar photovoltaic, and thermal power. Furthermore, it was used to determine the energy potential of each of the isolated areas, identifying those areas in which the SIRES could be implemented as a sustainable solution. The design simulates the cost of the initial investment and energy generation in the chosen areas. The study also includes the selection of different system components and the use of the general model to determine the optimal combination of energy subsystems for isolated areas with the aim of minimizing the cost of energy generations. Finally, an economic evaluation showed that the use of a SIRES based mainly on solar energy supported by biomass, biogas, and mini-wind power costs approximately three times less than extending the electricity grid network.

The Impact

Recently, as renewable and distributed power sources boost, many such resources are integrated into the smart grid as a clean energy input. However, since the generation of renewable energy is intermittent and unstable, the smart grid needs to regulate the load to maintain stability after integrating the renewable energy source. At the same time, with the development of cloud computing, large-scale datacenters are becoming potentially controllable loads for the smart grid due to their high energy consumption. In this paper, we propose an appropriate approach to dynamically adjust the datacenter load to balance the unstable renewable energy input into the grid. This could meet the demand response requirements by taking advantage of the variable power consumption of datacenters. We have examined the scenarios of one or more datacenters being integrated into the grid and adopted a stochastic algorithm to solve the problem we established. The experimental results illustrated that the dynamic load management of multiple datacenters could help the smart grid to reduce losses and thus save operational costs. Besides, we also analyzed the impact of the flexibility and the delay of datacenter actions, which could be applied to more general scenarios in realistic environments. Furthermore, considering the impact of the action delay, we employed a forecasting method to predict renewable energy generation in advance to eliminate the extra losses brought by the delay as much as possible. By predicting solar power generation, the improved results showed that the proposed method was effective and feasible under both sunny and cloudy/rainy/snowy weather conditions.

The integration of renewable energy is transcendental for sustainable development. This article analyses a hybrid grid-connected system composed of renewable energy technologies (photovoltaichydrokinetic), where several scenarios for energy management are proposed. They include a battery system as energy storage and a system without storage but with resale fee to grid, with the aim of determining the best economic and environmental balance. The results show that, by having a (PV-HKT-GRID) system with energy storage and no resale fee to the grid, the Net Present Cost (NPC) is increased by USD $ 132, 760 and the Cost of Energy (COE) decreases $ 0.013/kWh when compared to the grid. In addition, the same hybrid system without energy storage and no resale fee to grid, presents an energy cost savings of $ 0.043/kWh, and an additional cost of USD $ 43, 630. Finally, if a grid resale rate is included in the renewable hybrid system, then the difference is noticeable, the savings in the Cost of Energy is $ 0.073/kWh and presents a saving in the NPC of USD $ 39, 930. In all cases, CO2 emissions have been avoided.

Hybrid Renewable Energy

Hybrid Renewable Energy Systems (HRES) are an attractive solution for the supply of electricity in remote areas like islands and communities where grid extension is difficult. Hybrid systems combine renewable energy sources with conventional units and battery storage in order to provide energy in an off-grid or on-grid system. The purpose of this study is to examine the techno-economical feasibility and viability of a hybrid system in Donoussa island, Greece, in different scenarios. A techno-economic analysis was conducted for a hybrid renewable energy system in three scenarios with different percentages of adoption rate (20%, 50% and 100%)and with different system configurations. Using HOMER Pro software the optimal system configuration between the feasible configurations of each scenario was selected, based on lowest Net Present Cost (NPC), minimum Excess Electricity percentage, and Levelized Cost of Energy (LCoE). The results obtained by the simulation could offer some operational references for a practical hybrid system in Donoussa island. The simulation results confirm the application of a hybrid system with 0% of Excess Electricity, reasonable NPC and LCoE and a decent amount of renewable integration.
