Abstract-We address demand-side management of dispatchable loads in a residential microgrid by means of decentralized controllers deployed in each household. Controllers simultaneously optimize two possibly conflicting objectives: minimization of energy costs for the end user (considering a known, timedependent tariff) and stabilization of the aggregate load profile (load flattening). The former objective can be optimized independently by each controller. On the other hand, the latter could benefit from a communication infrastructure that allows the controllers to explicitly exchange information and coordinate.To study how different levels of communication pervasiveness affect system performance, we developed a realistic microsimulation environment accounting for the behavior of residents, dispatchable and non-dispatchable household loads, and the effects on the distribution network. We considered a generic model of communication among household controllers, not tied to any specific technology, and based on the partitioning of the households in a number of groups (neighborhoods). Controllers within the same neighborhood enjoy full connectivity, but cannot interact with controllers outside of their neighborhood. Through extensive simulation experiments, we observed that even communication neighborhoods constituted by as few as 3-4 households are sufficient to effectively stabilize the aggregate network load profile, with minimal bandwidth consumption. Increasing the neighborhood size leads to comparatively negligible performance improvements. We conclude that effective load flattening can be achieved with minimal requirements of communication infrastructure and transmitted information.

“…The FCPP produces as much thermal as electrical energy [57,58]. PEM fuel cells have various advantages that make them preferred relative to other fuel cells and permit them to be used in hybrid energy systems [59][60][61][62]. A sound strategy is necessary for management of excess electrical and/or thermal energy.…”

“…In this paper, the model in [14,48,59,61,62] is extended to include wind turbine, solar collector, and photovoltaic costs and revenues, so as to examine whether it is feasible to add wind turbines, solar PV panels and fuel cells to the local electrical grid serving a residential building in Iran. System operating costs can often be reduced through the utilization of such a hybrid renewable energy system and by connecting to the local electrical grid.…”

“…Specifically, the fuel cell is optimized by minimizing the system cost and maximizing the overall system income, causing the algorithms to utilize the fuel cell to satisfy the load when tariffs are high and the local grid when tariffs are low. Extensive information on fuel cell economics is available [59,61,64,65]. The function that is minimized, subject to the constraints outlined later, follows:…”

Optimal Operation of a Grid-Connected Hybrid Renewable Energy System for Residential Applications

Abstract:The results of a study on incorporating solar-thermal collectors into a hybrid renewable energy system are reported. A photovoltaic-wind turbine-fuel cell-solar-thermal collector system is designed and an economic model is introduced for supplying the residential thermal and electrical loads via the grid-connected hybrid system. Since determining the optimal operation of a hybrid system such as a combined heat and power system constitutes a complex optimization problem requiring a sophisticated optimization method, a modified heuristic approach-based particle swarm optimization is proposed for solving the optimization problem. The results are compared with those obtained by an efficient metaheuristic optimization method, namely a genetic algorithm, in terms of accuracy and run time. The results show that, using the grid-connected hybrid combined heat and power system, among the cases considered, decreases the total cost of the system. The results also demonstrate that the reductions in daily cost relative to the base case by the modified particle swarm optimization algorithm for Cases 1-4 are 5.01%, 25.59%, 19.42%, and 22.19%, respectively. Finally, Case 2 is the most cost-effective and reliable. Moreover, the modified particle swarm optimization algorithm leads to better results than the genetic algorithm.
