交互式能量系统的社会塑造
Social Shaping for Transactive Energy Systems
摘要：
本文考虑了在一个交易型能源系统中，如何塑造代理效用函数，以确保竞争均衡下的最优能源价格总是社会可接受的，即低于一个规定的阈值。分布式能源系统中的代理人的目标是最大化他们的个人收益，作为能源消耗的效用和能源交换的收入/支出的组合。每个代理的效用函数由个人偏好向量参数化，整个系统运行在竞争平衡。我们表明，社会塑造问题的建议transactive能源系统是概念上捕获的一组决策问题。一组代理偏好，保证社会上可接受的价格的特点是一个隐式代数方程的严格凹和连续可微的效用函数。我们还提出了两个分析解决方案，其中线性二次效用和分段线性效用的系数的严格范围内建立的最优定价被证明总是社会可接受的。
英文摘要：
This paper considers the problem of shaping agent utility functions in a transactive energy system to ensure the optimal energy price at a competitive equilibrium is always socially acceptable, that is, below a prescribed threshold. Agents in a distributed energy system aim to maximize their individual payoffs, as a combination of the utility of energy consumption and the income/expenditure from energy exchange. The utility function of each agent is parameterized by individual preference vectors, with the overall system operating at competitive equilibriums. We show the social shaping problem of the proposed transactive energy system is conceptually captured by a set decision problem. The set of agent preferences that guarantees a socially acceptable price is characterized by an implicit algebraic equation for strictly concave and continuously differentiable utility functions. We also present two analytical solutions where tight ranges for the coefficients of linear-quadratic utilities and piece-wise linear utilities are established under which optimal pricing is proven to be always socially acceptable.
