Hybrid Energy

A 100% renewable energy-based stand-alone microgrid system can be developed by robust energy storage systems to stabilize the variable and intermittent renewable energy resources. Hydrogen as an energy carrier and energy storage medium has gained enormous interest globally in recent years. Its use in stand-alone or off-grid microgrids for both the urban and rural communities has commenced recently in some locations. Therefore, this research evaluates the techno-economic feasibility of renewable energy-based systems using hydrogen as energy storage for a stand-alone/off-grid microgrid. Three case scenarios in a microgrid environment were identified and investigated in order to select an optimum solution for a remote community by considering the energy balance and techno-economic optimization. The “HOMER Pro” energy modelling and simulating software was used to compare the energy balance, economics and environmental impact amongst the proposed scenarios. The simulation results showed that the hydrogen-battery hybrid energy storage system is the most cost-effective scenario, though all developed scenarios are technically possible and economically comparable in the long run, while each has different merits and challenges. It has been shown that the proposed hybrid energy systems have significant potentialities in electrifying remote communities with low energy generation costs, as well as a contribution to the reduction of their carbon footprint and to ameliorating the energy crisis to achieve a sustainable future.

Hybrid Renewable Energy System

As India is a developing country which demands in more power requirement for the population. The conventional resources are also not making the requirement upto the needs of the customers. This brings our attention towards the nonconventional resources which includes renewable energy resources i.e., natural resources like sun, wind, ocean, geothermal, tidal etc. are some of the resources. Using this resources with the help of latest technologies we are equalizing the mismatch between the power generation and power demand. As far as the conventional power generation our country is performing great in the non- conventional means also, which results in the cost reduction of energy, carbon emission from the environment which will help a lot in the reduction of global warming. This paper presents the hybrid renewable energy system which consist of solar PV and wind energy system as generation unit and for the change of same traditional storage system here we are working with the pumped hydro storage system. All the system is being analyzed on the software for hybrid system known as Hybrid Optimization Model for Electrical Renewable (HOMER Pro).

Optimal Energy Management

The proposed optimal energy management system balances the energy flows among the energy consumption by accelerating trains, energy production from decelerating trains, energy from wind and solar photovoltaic (PV) energy systems, energy storage systems, and the energy exchange with a traditional electrical grid. In this paper, an AC optimal power flow (AC-OPF) problem is formulated by optimizing the total cost of operation of a railroad electrical system. The railroad system considered in this paper is composed of renewable energy resources such as wind and solar PV systems, regenerative braking capabilities, and hybrid energy storage systems. The hybrid energy storage systems include storage batteries and supercapacitors. The uncertainties associated with wind and solar PV powers are handled using probability distribution functions. The proposed optimization problem is solved using the differential evolution algorithm (DEA). The simulation results show the suitability and effectiveness of proposed approach.

Hybrid Energy Storage System

Abstract As the fossil energy crisis and environmental pollution become more and more serious, clean renewable energy becomes the inevitable choice of energy structure adjustment. The power system planning and operation has been greatly influenced by the instability of the power output of distributed renewable energy systems such as solar energy and wind energy. The hybrid energy storage system composed of accumulator and supercapacitor can solve the above problems. Based on the analysis of the energy storage requirements for the stable operation of the DC microgrid, battery–supercapacitor cascade approach is adopted to form hybrid energy storage system, in a single hybrid energy storage subsystem for battery and supercapacitor and in the microgrid system of different hybrid energy storage subsystem, respectively, and puts forward the corresponding power allocation method to realize the smooth control of the battery current, to reduce the battery charge and discharge times, to prolong the service life of battery and to improve the running stability of the microgrid.

Abstract Integrating marine renewables and aquaculture is a complex task. The generated power of each renewable technology depends on its source cycle (wind, wave, solar PV), leading to periods of zero power production. On the other side, aquaculture farms require smooth and stable power supply since any power shortage can lead to the loss of the entire farm production. This paper illustrates the sizing of a hybrid energy system (wind,solar PV, energy storage) to power up the aquaculture farm. The sizing is based on available commercial technology and the system is mounted on a single multi-purpose platform. Reliability is improved by considering device redundancies. Such hybrid system has not been considered before for aquaculture farms. System rough sizing, based on simple online renewable energy calculators, is used to select existing renewable technologies and HOMER Pro simulation software is used to evaluate the technical and economic feasibility of the microgrid for all possible combinations of the technology selected and perform sensitivity analysis on wind turbine tower height, battery state of charge and solar PV panels reflectance. The optimisation is subject to combined dispatch strategy and net present cost.

Renewable energy resources are contributing evermore to the generation mix worldwide, however, expanding grids in size and complexity have given rise to unforeseen complications such as frequency oscillations, voltage sags and spikes, and power outages. In 2013, nearly 100% of electricity generation in Iceland was from hydropower and geothermal sources; there is also high potential for wind and tidal energy, both options are being explored and would benefit from additional technologies to manage fluctuations and store energy surplus. Landsnet is the sole transmission system operator (TSO) responsible for energy balance in Iceland. On the consumer side, load variations represent difficulties for utilities to meet ever-changing demand. Research indicates high-capacity electricity energy storage (EES) has the potential to be economically beneficial as well as carbon neutral, all while improving power and voltage quality, peak-shaving, reducing the number of grid failures and reducing natural fluctuations in renewable energy (RE) sources. Two complex resource deployment scenarios are modeled using GridCommand™ Distribution: (1) large-scale 10 MWh capacity EES evenly distributed across the transmission system, and (2) large-scale 10 MWh capacity EES clustered at targeted substations in the transmission system. Results reveal 10 MWh capacity battery EES at a density of 60% in the transmission model provides optimal performance conditions. Optimal conditions are defined by EES performance metrics, and signify improvements in power quality, energy balance, and peak-shaving when electricity demand is at its highest. EES technologies are presented and tested at different locations across the Icelandic grid to predict which solutions are best for the future development of the electricity system.
