“…There are four types of parallel computing which are bit-level parallelism, instruction-level parallelism, task parallelism, and super word-level parallelism. Parallel computing algorithm can solve the operating state of every microgrid at the same time considering the interaction between the different microgrids in a multi-microgrid system and this technique improves the speed of calculation significantly in attaining the reliability of the system [101]. The inter-temporal restrictions, such as the generators' ramp rates and the state of charge of the ESSs, have a substantially bigger impact on the system since microgrids have a comparatively high mix of renewable energy sources and energy storage systems (ESSs) compared to existing large-scale power systems.…”

The microgrid is the modern solution for power surges and blackouts as it can act as a standalone system when the grid is under attack as it works along with the grid which helps in achieving higher reliability of the system and also helps to overcome existing problems associated with a grid to reach out remote areas but unlike advantages, there are disadvantages for this kind of system to overcome such as reliability, quality and continuity. When it is considered in a contest of power systems, The major uncertainties are nonlinear, nonconvex, and mixed-integer problems, hence to overcome such types of uncertainties there is a need to develop an optimization technique that can help to reduce the effect on generation and dispatch of power. Microgrid systems which comprised of renewable energy resources such as wind, solar and battery storage units that can be connected to the grid & also can act as a standalone system. This paper reviews the different soft computing techniques involved in optimizing the power system & furthermore, the appropriate & most efficient soft computing technique is determined as well as future scope of these techniques is discussed.

“…Adopting the method of multi-step calculation on the basis of parallel calculation can achieve the purpose of improving the simulation efficiency [9] . Using a longer step for the device with a simple model and a shorter step for the device with a complex model can reduce the amount of calculation and speed up the simulation.…”

“…An optimization algorithm based on a parallel computing mechanism is proposed, which shortens the optimization time to one-tenth of the traditional algorithm. Reference [9] proposes a reliability evaluation algorithm based on the parallel computing algorithm of the multi-microgrid system. The algorithm can significantly improve the calculation speed of the reliability assessment algorithm of the multi-microgrid system.…”

Electricity-hydrogen coupled DC microgrid is of great significance for energy structure adjustment and efficient consumption of renewable energy. However, at present, such systems lack high-precision simulation support, and the transient simulation technology for large-scale microgrid systems is not perfect. In order to solve these problems, this paper form an electricity-hydrogen coupled DC microgrid simulation platform, and studies the function realization and the efficiency improvement of transient simulation. Firstly, the Euler algorithm is adopted to realize the transient simulation of the microgrid system for the functional requirements of the electricity-hydrogen coupled DC microgrid. Secondly, for different system sizes and computing platforms, an adaptive parallel computing optimal mode selection algorithm is proposed to improve the simulation efficiency. The experimental results show that the algorithm improves the computing efficiency of the large-scale electricity-hydrogen coupled DC microgrid system by about 40%.

In most of the institutional buildings solar photovoltaic (PV) systems are used for fulfilling the local energy requirement. In this work, a typical institution with solar PV and battery energy storage is selected for analyzing the system’s operation to fulfil the institutional energy demand. To operate this energy system as a micro-grid, distributed generator is selected for fulfilling the institutional load demand in coordination with PV, battery and during the grid outage time. The operation of distributed generator has improved the system performance and coordinated the contribution among local energy resources e.g. PV energy and battery throughput. In this work, relative analysis of the intuitional energy system with and without distributed generator has been analyzed for annual load profile. It has been observed; the distributed generator is not only useful for supplying the energy to the essential load but also during the grid outage conditions. The analysis shows that if, the grid outage continues for longer period then distributed generator can provide the power to the institutional load and operate as a micro-grid. It has been observed, the battery energy throughput as well as effective utilization of local energy resources can be improved by installing distributed generator. The presented analysis is going to be useful for operating the institutional energy system as a micro-grid with different energy and power management strategies.
