我们研究可再生能源渗透率较高的新兴配电级能源市场的市场结构。众所周知，可再生能源发电具有不确定性，并且边际成本接近于零。在本文中，我们使用太阳能作为我们重点研究的零边际成本资源的例子。我们首先表明，在太阳能发电的高渗透率下，经典的实时市场机制要么会表现出显着的价格波动（当不允许每个企业改变供应数量时），要么会导致价格固定（当允许每个企业改变供应数量时），后者会导致剩余分配的极端不公平。为了克服这些问题，我们提出了一种新的租赁市场机制，该机制可以交易太阳能电池板的使用权，而不是实时太阳能。我们表明，租赁市场产生稳定且独特的价格（因此消除了价格波动），为消费者和企业保持正盈余（因此消除了价格固定），并实现了与传统实时市场相同的社会福利。一个关键的见解是，租赁市场将可再生能源发电的不确定性从不利因素（导致实时市场价格波动）转变为有利因素（增加需求弹性并有助于实现理想的租赁市场结果）。
We study the market structure for emerging distribution-level energy markets with high renewable energy penetration. Renewable generation is known to be uncertain and has a close-to-zero marginal cost. In this paper, we use solar energy as an example of such zero-marginal-cost resources for our focused study. We first show that, under high penetration of solar generation, the classical real-time market mechanism can either exhibit significant price-volatility (when each firm is not allowed to vary the supply quantity), or induce price-fixing (when each firm is allowed to vary the supply quantity), the latter of which leads to extreme unfairness of surplus division. To overcome these issues, we propose a new rental-market mechanism that trades the usage-right of solar panels instead of real-time solar energy. We show that the rental market produces a stable and unique price (therefore eliminating price-volatility), maintains positive surplus for both consumers and firms (therefore eliminating price-fixing), and achieves the same social welfare as the traditional real-time market. A key insight is that rental markets turn uncertainty of renewable generation from a detrimental factor (that leads to price-volatility in real-time markets) to a beneficial factor (that increases demand elasticity and contributes to the desirable rental-market outcomes).
