As the population of urban areas continues to grow, and construction of multi-unit developments surges in response, building energy use demand has increased accordingly and solutions are needed to offset electricity used from the grid. Renewable energy systems in the form of microgrids, and grid-connected solar PV-storage are considered primary solutions for powering residential developments. The primary objectives for commissioning such systems include significant electricity cost reductions and carbon emissions abatement. Despite the proliferation of renewables, the uptake of solar and battery storage systems in communities and multi-residential buildings are less researched in the literature, and many uncertainties remain in terms of providing an optimal solution. This literature review uses the rapid review technique, an industry and societal issue-based version of the systematic literature review, to identify the case for microgrids for multi-residential buildings and communities. The study describes the rapid review methodology in detail and discusses and examines the configurations and methodologies for microgrids.

“…Additionally, galvanic isolation is added by using transformers. Power converters usually inject and absorb reactive power and further participate in voltage stability [17,21,25]. Moreover, in some cases, commercially available grid-connected PV inverters also support voltage stability, reactive power and anti-islanding functions [16].…”

“…The present‐day transformation means a significant and structural change for the whole system 1 . Power generation based on renewable energy sources is constantly increasing both among the large power plants, and in the distributed manner: more and more consumers become so‐called prosumers (producer and consumer), since they buy and utilize household power generating units, energy storage systems, electric vehicles, or intelligent household devices 2 . These new technologies, market players, and consumer behavior change push the boundaries of the traditional electricity supplier and its market model 3…”

“…Microgrids could offer a viable solution as a local integration platform. Beyond technological challenges, the spread of local power generation could lead to the formation of communities (or local energy communities, citizen energy communities), 2,6 which—although the communities interact with the network—could cause significant losses to the DSO in the system usage fee according to present grid tariffs 7 . Therefore, there is an increasing need either for the networks to operate independently of the synchronous area, or for loosely connected networks to improve the quality and continuity of power supply 8,9 .…”

Summary Arguably, the most important challenge nowadays in the energy industry is the utilization of intermittent renewable energy sources. On the one hand, renewable sources are the future in terms of sustainability. While on the other hand, several questions remain unanswered in connection with their day‐to‐day operation and system integration. Creating microgrids with local control of the distributed energy resources seems to offer solutions but there is a lack of practical experience. Especially in Europe, where a microgrid with islanding capability is connected to a widespread, synchronously operating grid, it is a complicated task, owing to the control methods. In this paper, the technical possibilities are presented, which are necessary to allow island mode operation of a microgrid. The case study discusses a “living lab” in which several energy generation technologies have been deployed thus it is a good representation of future renewable‐based microgrids. To support the island operation, numerical calculations and simulations are used to determine power and energy needs of necessary flexibility measures. Basis of the calculations is the year‐long data measured on‐site. Sizing and operation modes for energy storage and demand‐side resources and an architectural scheme are presented. Net present value for all technological options are compared to aid the selection of the best option. A sensitivity analysis is also performed to assess how potential change in various parameters of the economical calculation affect the results. It is shown that provision of uninterruptible power supply and thus island operation of the site can be provided within reasonable techno‐economical limits.

“…Moreover, the underlying network of a typical energy island is vulnerable to severe instability issues, because: (i) its interconnection point with higher voltage networks (i.e., main grid at the transmission network level) is weak, and (ii) its existing lines at the distribution network level are usually inadequate to accommodate the continuously increasing RES, especially at the edges of the low-voltage distribution network [5]. Finally, when not operating in islanded mode, the Microgrid Operator (MGO) purchases/sells energy from/to the main grid to cover/sell its excessive demand/supply.…”

Network and Market-Aware Bidding to Maximize Local RES Usage and Minimize Cost in Energy Islands with Weak Grid Connections

et al. 2020

The increasing renewable energy sources RES penetration in today’s energy islands and rural energy communities with weak grid connections is expected to incur severe distribution network stability problems (i.e., congestion, voltage issues). Tackling these problems is even more challenging since RES spillage minimization and energy cost minimization for the local energy community are set as major pre-requisites. In this paper, we consider a Microgrid Operator (MGO) that: (i) gradually decides the optimal mix of its RES and flexibility assets’ (FlexAsset) sizing, siting and operation, (ii) respects the physical distribution network constraints in high RES penetration contexts, and (iii) is able to bid strategically in the existing day-ahead energy market. We model this problem as a Stackelberg game, expressed as a Mathematical Problem with Equilibrium Constraints (MPEC), which is finally transformed into a tractable Mixed Integer Linear Program (MILP). The performance evaluation results show that the MGO can lower its costs when bidding strategically, while the coordinated planning and scheduling of its FlexAssets result in higher RES utilization, as well as distribution network aware and cost-effective RES and FlexAsset operation.
