Special Issue Information

Dear Colleagues,

We would like you to consider submitting a paper for this Special Issue of the journal Buildings; the focus of which is on the integration of microgrid’s systems in buildings. The distributed energy generation shows a very rapid growth and reveals an increasing complexity for grid’s managers due mainly to prosumer sites, i.e. producer and consumer buildings. The intermittent nature of renewable energy sources, e.g. photovoltaic generator, remains an issue for their integration into the public grid resulting in fluctuations of voltage and/or frequency, harmonic pollution, difficulty for load management, etc. To increase their integration level and obtain a robust power grid, the smart grid could solve problems of peak consumption, optimal energy management, and demand response. The smart grid is being designed primarily to exchange information on grid needs and availability, help balancing power, avoid undesirable injection, and perform peak shaving. Microgrids, consisting of renewable and traditional energy sources, storage systems, and adjustable loads, play an important role in distributed energy generation and ancillary services. A microgrid controller interacts with the smart grid; it provides voltage control, power balancing, load sharing or load shedding, and takes into account the constraints of the public grid provided by smart grid communication. Therefore, facing the emergence of the smart grid combined with AC or DC microgrids and the increase in positive-energy buildings, one of the solutions is building integrated microgrid systems which provides a solution for the self-supply of buildings, electric vehicles, and grid-interaction control.

We hope this subject is of interest to you and look forward to collaborating with you in the near future.

Recently, the use of DC microgrid distribution system has become more attractive than traditional AC systems due to their energy efficiency and ability to easily integrate with renewable energy sources and batteries. This paper proposes a 500 V DC microgrid which consists of a 20 kWp photovoltaic panel, batteries, and DC loads. A hierarchical control strategy to ensure balance power of the DC microgrid and the maintenance of common DC bus voltage is presented. The capability of exchanging power energy of the microgrid with the power system of neighborhood buildings is also considered. Typical operation modes are simulated in the Matlab/simulink environment to confirm the good performance of the controllers and the efficiency of appropriately controlling the charge–discharge of the battery system. This research is expected to bring benefits to the design and operation of the system, such as reducing the capacity of batteries, increasing the self-supply of buildings, and decreasing the electricity demand from the AC grid.

The microgrid system is an answer to the necessity of increasing renewable energy penetration and also works as a bridge for the future smart grid. Considering the microgrid system applied to commercial building equipped with photovoltaic sources, the usage of a DC microgrid architecture can improve the efficiency of the system, while ensuring robustness and reducing the overall energy cost. Given the power grid stress and the intermittency of the DC microgrid power production, backup power provision and load shedding operations may occur to stabilize the DC bus voltage. Based on the knapsack problem formulation, this paper presents a realistic optimization approach to shedding a building’s appliances, considering the priority of each appliance, and also considering a minimum amount of load that must be attended. The problem is solved by mixed integer linear programming and the CPLEX solver. The proposed architecture ensures critical load supply and voltage stabilization through the real-time operation of the operational algorithm allowing the load shedding optimization approach to be applied without compromising the robustness of the system. The results obtained by simulation prove that the DC microgrid is able to supply the building power network by applying the load shedding optimization program to overcome, mainly, the renewable energy intermittency.
