管制市场中激励分布式能源发电的电能虚拟存储政策（英文）

Electrical Power Virtual Storage Policy for Stimulating Distributed Generation in Regulated Markets

可再生、清洁能源分布式发电(distributed generations,DGs),是能源、环境可持续发展的重要途径之一。在管制的电力市场中,用户自建分布式能源会影响自然垄断的电网企业的利益。中国国家电网公司已经开放DG并网,为此,需对DG并网后的计量、计费、管理政策等进行深入研究,提出一种适应管制电力市场的电能虚拟存储政策模型来推行电能虚拟存储政策。该模型应能确保用户自建分布式能源对电力企业利益的影响在其可接受范围之内,而且能够最大程度激励用户自建分布式能源。然后通过对该政策模型的参数优化确定了最优模型参数和所有用户自建分布式能源的容量。为促进该项政策的实施,在不同的阶段,通过提高允许的政策参数,逐步提升对用户自建分布式能源的激励力度。最后通过算例验证了所提模型的适应性和有效性。

The application of renewable and clean distributed generations（DGs） is one of the important measures taken to solve the problem of energy shortage and environment pollution. In regulated electricity market, the integration of consumers＇ self-built DGs may harm the interests of the power utilities under present policies. The State Grid Corporation of China has claimed that it will try its best to accommodate the integration of DGs. In order to realize the objective, further research about measurement, accounting and management policy is still needed. In this paper, electrical power virtual storage policy model was proposed to promote the policy in regulated electricity market. The model can ensure the influence resulting from self-built DGs is within the agreed scope and encourage consumers to build DGs as more as possible. Then the optimal policy parameters and the total capacity of all the consumers＇ self-built DGs were determined by parameter optimization in the policy model. To implement the policies, the incentive strength on consumers＇ self-built DGs is promoted by improving the allowed policy parameters at different stages. The case study shows that the proposed model is adaptable and effective.
