Abstract

Having achieved a significant share of renewable generation in different sectors of society, forming Energy Communities (EC) is the next step towards energy sustainability. The energy and economic performance of EC depends on several factors. These include electricity tariffs, members’ consumption profiles, available generation/storage, and the type of generation ownership.

This study analyzes the variations in economic benefits among EC members and the EC as a whole. The study is based on a simulation of an EC ’s operation in Bogota, Colombia applying current regulations. Four scenarios are evaluated (Conventional, Non-cooperative with renewable energy, Cooperative with centralized renewable energy, and, Cooperative with centralized/distributed renewable energy). The members of the CE are residential and commercial consumers.

The annual cost of electricity (COE) is used to measure the operational efficiency of the EC. The results of the simulations indicate that, varying the ownership of the generation sources within the EC, ceteris paribus, the total COE of the EC is constant. The change is observed in the distribution of profits among the EC members. Due to the priority given to self-consumption, members who own generation sources obtain greater profits than community generation source users.

A methodology has been developed to assess the impact of a new member joining on the individual and group energy and economic management of an EC that is already operating. A quick and simple indicator has been obtained about the potential benefit that a new member can bring to the already operational EC. To do this, it is only necessary to know the annual energy consumption to compare it with the maximum self-consumption of the original members. The results obtained in the scenarios analysed indicate that the proposed indicator is very close to the result obtained through complete scenario simulations, demonstrating the usefulness of the proposed indicator.

评估能源社区成员用电成本的方法

在可再生能源发电在社会不同部门中占有相当大的份额之后，组建能源社区（EC）是实现能源可持续性的下一步。EC的能源和经济性能取决于几个因素。这些包括电价、成员的消费概况、可用的发电/存储以及发电所有权的类型。本研究分析了欧共体成员国之间以及欧共体整体经济效益的差异。这项研究是基于对哥伦比亚波哥大一家电子商务公司实施现行法规的模拟。评估了四种情景（常规、与可再生能源不合作、与集中式可再生能源合作、与集中式/分布式可再生能源合作）。行政长官的成员包括住宅和商业消费者。年度电力成本（COE）用于衡量EC的运行效率。仿真结果表明，在其他条件不变的情况下，在不同的发电源所有权条件下，EC的总COE是恒定的。这种变化体现在欧共体成员国之间的利润分配上。由于优先考虑自我消费，拥有发电源的成员比社区发电源用户获得更大的利润。已经制订了一套方法，以评估新成员加入对已经运作的共同体的个人和团体能源和经济管理的影响。已经获得了一个快速和简单的指标，表明新成员可以给已经运作的欧共体带来潜在的好处。要做到这一点，只需要知道每年的能源消耗，并将其与原始成员的最大自我消耗进行比较。在分析的情景中获得的结果表明，所提出的指标与通过完整情景模拟获得的结果非常接近，表明所提出的指标的有用性。
