“…442 Polynomial mutation operator [87] and simulated binary crossover operator [88] are used along with differential 443 evolutionary operators [77]- [79]in the reproduction of the population. Constraints for the optimization algorithm are 444 handled at two different levels: constraint tournament method [87] is used to handle the constraints in the 445 optimization algorithm and loss of load probability is considered as a constraint while states of the control system 446 were defined to handle the constraints due to grid curtailments.…”

“…When the price of electricity in the grid increases further, it is 384 economical to discharge the battery bank in addition to directing excess electricity generated ( Designing electric hubs integrated to the grid is challenging due to a number of reasons as discussed before. A 395 heuristic algorithm has been amply used in the literature [19], [32]- [34], [39], [79]- [81] and shown to be much 396 efficient when optimizing these systems when compared to enumerative methods [82] which are used in existing 397 software such as Homer [83]. A detailed comparison of these methods can be found in recent reviews on hybrid 398 energy system designing [80], [84].…”

9A paradigm change in energy system design tools, energy market, and energy policy is required to attain the target 10 levels in renewable energy integration and in minimizing pollutant emissions in power generation. Integrating non-11 dispatchable renewable energy sources such as solar and wind energy is vital in this context. Distributed generation 12 has been identified as a promising method to integrate Solar PV (SPV) and wind energy into grid in recent literature. 13Distributed generation using grid-tied electrical hubs, which consist of Internal Combustion Generator (ICG), non-14 dispatchable energy sources (i.e., wind turbines and SPV panels) and energy storage for providing the electricity 15 demand in Sri Lanka is considered in this study. A novel dispatch strategy is introduced to address the limitations in 16 the existing methods in optimizing grid-integrated electrical hubs considering real time pricing of the electricity grid 17 and curtailments in grid integration. Multi-objective optimization is conducted for the system design considering 18 grid integration level and Levelized Energy Cost (LEC) as objective functions to evaluate the potential of electrical 19 hubs to integrate SPV and wind energy. The sensitivity of grid curtailments, energy market, price of wind turbines 20 and SPV panels on Pareto front is evaluated subsequently. Results from the Pareto analysis demonstrate the potential 21 of electrical hubs to cover more than 60% of the annual electricity demand from SPV and wind energy considering 22 stringent grid curtailments. Such a share from SPV and wind energy is quite significant when compared to direct 23 grid integration of non-dispatchable renewable energy technologies. 24

Abstract:The need for reduction in power consumption for public facilities has increased after the occurrences of multiple blackout events. In an effort to enable the development of green and smart social infrastructure, this paper introduces a design for a sustainable and efficient transportation system (SETS). For this design, renewable power sources and efficient electric drives are considered to be crucial technologies. Considering the subway station as an illustrative example, a power system design that uses wind and solar energy as major power sources is studied. The adjustable speed electric drive system that uses synchronous reluctance machines for ventilation systems contributes to increasing the overall power consumption efficiency. The effectiveness of the proposed SETS system is verified through a set of various field measurement data and simulation results. While the verification results demonstrate that operation of SETS is enabled by effective integration of renewable sources and efficient ventilation systems, future research directions have also been identified.

“…This (unpredictable) uncontrollability in output power of most of RES can be somehow mitigated by introducing a storage component to RES in order to decouple the instantaneous generation from the consumption. A Hybrid Renewable Energy System (HRES) is defined as a system consisting of single/multiple RES along with a (or a combination of several) storage element(s) [1]. Some examples are commercialized stand-alone solar-battery configuration for street lighting, or a wind-solar-fuel cellhydrogen storage configuration for electrifying a remote rural area or an island.…”

Abstract-The intermittent and fluctuating nature of output power of renewable energy sources (RES) can lead to serious security concerns such as congestion in the transmission system. Incorporating storage devices with RES is technically an effective means to mitigate this concern by allowing fluctuating RES to be as stable as traditional power plants. Storage is an even more consumer-friendly solution with greater control over electricity consumption time and price compared to e.g. demand-side management which offers limited control over the price for end users. It can also contribute to lower the electricity price, peak-shave the demand, defer upgrade investments, provide ride-through solution for (momentary) faults, contribute to voltage/frequency control, increase the share of green energy and thus reduce overall greenhouse gas emissions, improve power quality by reducing harmonic distortions and voltage sags/surges, facilitate utilization of more efficient off-peak generation units, etc. This paper assesses the technical applicability and economical viability of different storage devices to the Belgian power network, focusing on the structure of the Belgian electricity market. A high-level overview of widely-used storage technologies, their benefits and shortcomings are also provided.
