The distribution of renewable energy resources (RERs) is currently uneven and is largely influenced by their affordability across various communities. This has led to disparities in access to green energy for different community members. To address these inequalities, this study proposes an equity-oriented power-sharing mechanism that incorporates demand response (DR). The implementation of this approach will increase the availability of green energy for all members of the community in mixed neighborhoods. First, a DR program is introduced for conventional homes (i.e., homes without RERs) to maximize the consumption of RERs by shifting their load to RER excess intervals. Then, a proportionally fair mechanism is introduced to distribute the available resources among community members during times of high excess. The objective is to minimize the grid dependence of community members by reducing their reliance on purchasing power from the grid. To ensure renewable energy homes (i.e., homes with installed RERs) maintain their green energy access, additional constraints are put in place to prioritize their energy needs when compared to the non-sharing case. Three indices (green energy access, grid dependence, and cost reduction) are introduced to evaluate the performance of the proposed method in different cases: the base case, the power-sharing-only case, and the case of power-sharing with the DR. Finally, the impact of different seasons, day types, and user-defined parameters is analyzed. Simulations have shown that the proposed method can significantly increase the green energy access of conventional homes without affecting the access to green energy of renewable energy homes. It also decreases the grid dependence and the electricity cost of the entire community.

以公平为导向的电力共享和需求响应，以增强混合社区的绿色能源获取

目前可再生能源资源（RER）的分布不均匀，很大程度上受到各个社区的承受能力的影响。这导致不同社区成员在获得绿色能源方面存在差异。为了解决这些不平等问题，本研究提出了一种包含需求响应（DR）的以公平为导向的权力分享机制。这一方法的实施将增加混合社区所有社区成员获得绿色能源的机会。首先，针对传统家庭（即没有 RER 的家庭）引入 DR 计划，通过将负载转移到 RER 超额区间来最大化 RER 的消耗。然后，引入按比例公平的机制，在高过剩时期在社区成员之间分配可用资源。目标是通过减少社区成员对电网购买电力的依赖，最大限度地减少社区成员对电网的依赖。为了确保可再生能源家庭（即安装了 RER 的家庭）保持其绿色能源供应，与非共享情况相比，需要制定额外的限制来优先考虑其能源需求。引入三个指标（绿色能源接入、电网依赖和成本降低）来评估所提出方法在不同情况下的性能：基本情况、仅电力共享情况和与 DR 电力共享情况。最后，分析了不同季节、日期类型和用户定义参数的影响。仿真结果表明，所提出的方法可以显着增加传统家庭的绿色能源获取，而不影响可再生能源家庭对绿色能源的获取。它还降低了整个社区对电网的依赖和电力成本。
