“…PV, HKT, BB, and DG, are connected to a common DC bus through power converters for energy management. The application of SDO optimization techniques to the system sizing chosen validates the reliability of the system [8]. Figure 5 displays the estimation of electricity consumption per hour from the characteristic curve of the Ecuadorians' residential consumption [31].…”

Abstract:Rural electrification is one of the most significant issues faced by electricity companies. For this reason, these companies are choosing alternative sources to generate energy in isolated regions. Furthermore, hybrid generation systems are an effective option for supplying protected areas. In this context, this research aims at designing an autonomous hybrid system to meet the annual electricity demand of the inhabitants of a national park. Fluvial and solar energies are the best options to reduce environmental impact and to ensure the conservation of the endemic fauna and flora of the island at a low carbon footprint. The system comprises a series of subsystems modeled using commercial software for sizing and optimization. The main generation subsystem contains a hydrokinetic turbine and photovoltaic panels, the storage subsystem contains a battery bank, and the backup subsystem consists of a diesel generator used in case of lack of energy from the rest of suppliers of the hybrid system. The main results of the simulation show an optimized system that fulfills the energy demand while minimizing the use of the diesel generator to 5668 kWh/year (14.3%) of thorough generation. The hydrokinetic generator supplies 20,330 kWh/year (51.4% of the total generation) and the solar generator supplies 13,580 kWh/year (34.3%).

“…As shown in this section, the use of DES for renewable energy integration is an active research field centred mainly on the development of scheduling strategies and on the definition of optimal sizing for each application. This is shown also by the presence of several commercial packages such as HOMER, HOGA, TRNSYS and RETScreen and others as summarised in [28] and [29]. Anyway, historical wind speed measurement must be used in sizing and when these are not available, inputs are calculated from Weibull distributions as verified in [30], losing the autocorrelation of wind speed time series.…”

Storage sizing for grid connected hybrid wind and storage power plants taking into account forecast errors autocorrelation

International audienceThis paper describes a research on the influence of wind power prediction error autocorrelation on the sizing of storage coupled with a wind farm. The stochastic nature of renewable energies resources such as wind speed or solar radiation represents a challenge for the grid integration of renewable energy plants. The imbalances between renewable power predictions and realised production are generally penalised by system operators since additional reserves are required to maintain the stability of the grid. The coupling of storage devices with renewable energy plants is one of the solutions studied to reduce those imbalances. In this work, a methodology to manage imbalances and to size storage in order to achieve a determined level of controllability is proposed. It is applied to a specific use case: the integration of a combined wind-storage plant in French Guyana. The influence of the autocorrelations of errors on the battery size is investigated in detail and a methodology for producing wind prediction errors time series is presented

“…As an efficient search method, HS has simple concept, is easy to implement, can escape local optima by use of probabilistic mechanisms, and only needs one initial solution to start its search. For performance evaluation, the results of HS are compared with the results found by discrete simulated annealing (SA) algorithm and HOMER software [4,26]. HOMER (Hybrid Optimization Model for Electric Renewables) is able to optimize stand-alone hybrid systems integrating renewable energies (WG and PV), backup and storage systems based on hydrogen and batteries, and DC and/or AC loads [26].…”
