A review of optimal operation of microgrids

Abstract

The term microgrid refers to small-scale power grid that can operate autonomously or in concurrence with the area’s main electrical grid. 
 The intermittent characteristic of DGs which defies the power quality and voltage manifests the requirement for new planning and operation approaches for microgrids. Consequently, conventional optimization methods in new power systems have been critically biased all through 
 the previous decade. One of the main technological and inexpensive tools in this regard is the optimal generation scheduling of microgrid. As a primary optimization tool in the planning and operation fields, optimal operation has an undeniable part in the power system. This paper reviews and evaluates 
 the optimal operation approaches mostly related to microgrids. In this work, the foremost optimal generation scheduling approaches are compared in terms of their objective functions, techniques and constraints. To conclude, 
 a few fundamental challenges occurring from the latest optimal generation scheduling techniques in microgrids are addressed.

Hybrid Renewable Energy Microgrid for a Residential Community: A Techno-Economic and Environmental Perspective in the Context of the SDG7

“…Hence, considering these are essential while planning MGs [11,12]. The availability of abundant RERs in India provides a high possibility of harnessing these sources as an alternative for remote area electrification [10][11][12][13]. The energy conversion systems like PV, and wind turbine (WT) can be used in combination by making hybrid configurations, especially MGs or hybrid renewable energy systems (HRES).…”

“…The energy conversion systems like PV, and wind turbine (WT) can be used in combination by making hybrid configurations, especially MGs or hybrid renewable energy systems (HRES). These hybrid configurations will improve system reliability and performance while decreasing fluctuations in the generation, investment costs, and storage system size [11,13]. During the grid-independent operation, the off-grid hybrid system may not be able to support the full load; therefore, ESSs provide the backup energy needs during conditions of variable output power from the RERs [13][14][15][16][17].…”

“…values. Parameter values of the configurations are taken from [15], [19], [21]- [26] and listed in Table 1. Simulation time for the system is taken to be 300s.…”

Optimal operation management of grid-connected microgrids under uncertainty

“…The survey on existing research works on the optimal strategies for the operation of MGs is proposed in [3]. Reference [4] reviews and compares different optimization techniques applied for achieving optimal operation of MGs from diverse perceptions, in terms of objective functions, optimization techniques, constraints and computational performances. An operation optimization modeling for a MG considering the distributed generation, environmental factors and DR is proposed in [5].…”
