摘要
在电力现货市场中,现货电价时常会出现的大幅度波动使得售电公司的购电成本高于售电收入。为提高售电公司的运营风险抵御能力,考虑了电动汽车用户购电对售电公司收益的影响,提出了一种售电公司购买电动汽车备用容量的经营策略。在该策略下,售电公司通过购买电动汽车备用容量以获得购售电裕度。当售电公司由于现货市场电价波动出现亏损时,可调用电动汽车备用容量改变负荷量,从而达到降低损失的目的。算例表明该策略可一定程度上降低售电公司运营风险。
A electric power spot market, spot power price always fluctuates sharply, which results in electricity purchasing cost of the electricity retail company higher than its electricity selling income. A order to improve operating risk resistance ability of the electricity retail company, on the basis of considering influence of electricity purchase of electric vehicle users on earnings of the electricity retail company, the paper proposes a kind of operating strategy of purchasing reserve capacity of electric vehicles. Under this strategy,the electricity retail company can obtain electricity purchase margin by purchasing reserve capacity of electric vehicles. When the electricity retail company is defective due to fluctuation of power price in the spot market, it can reduce its losses by using reserve capacity of electric vehicles to change load. Example indicates this strat-egy can reduce operating risk of the electricity retail company to a certain extent.
