Sharing distributed energy resources in apartment buildings: the winner takes it all?
Solar generation is one of the key technologies in decarbonizing and decentralizing the energy system. While solar PV on single-family houses is well-established and integrated solution, there have been relatively few such installations on multi-unit apartment buildings so far. Also, with the rapid Urbanisation, cities - mostly with a high share of apartment buildings - are becoming the largest energy consumers globally. Hence, to address the energy-climate challenge innovative solutions have to be developed to make better use of distributed energy resources (DERs) in urban locations. By comparing apartment buildings with single-family houses, multiple differences can be identified: a higher number of consumers (owners/tenants) are involved; consumers have to agree on an energy allocation method, because they share a common energy resource (e.g., solar PV, possibly combined with energy storage); individual consumer objectives have to be taken into account with the possibility of conflicting objectives between different parties; interactions with the surrounding system (local power grid, utility, electricity market) must be considered. Publications in the literature address solar generation in multiple ways. Up to now, the studies focus on topic like grid parity, the power system´s perspective or grid integration concepts. In the recent years, advanced concepts and allocation schemes have been developed for microgrids, often times using game theoretical approaches. Consequentially, we will further improve these applications and develop a framework for apartment houses. While many studies are dealing with multiple households and DERs, our study will, focus on one solar generation plant in combination with a battery as a shared energy resource one apartment building. The novelty of this work is that we consider the consumers´ preferences by allowing them to adjust the weights for multiple objectives in choosing between different energy resources. Additionally, we will develop a bi-level optimization model clearing and pricing local generation and consumptions. The building has a shared solar PV plant, and we also consider battery as shared energy storage resource. We define a set of individual consumer preferences and search for the optimal allocation of local and grid energy resources. The paper is organized in following way. In Section 2, we will introduce a framework for sharing DERs in apartment house. Section 3 includes the data assumptions for an illustrative example, while Section 4 shows the results. Section 5 discusses and concludes the paper.
