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。
Renewable and Clean Energy Distributed generations (DGs) are one of the important ways for the sustainable development of energy and environment. In the regulated electricity market, users self-built distributed energy will affect the interests of natural monopoly power grid companies. China’s State Grid Corporation of China has already opened the DG grid. Therefore, it is necessary to make an in-depth study on the measurement, billing and management policies of DG after grid connection and put forward a virtual storage policy model of electric energy to control the electricity market to promote the virtual storage of electric energy policy. The model should ensure that the user-generated distributed energy has an acceptable impact on the interests of power companies and that it can maximize the user-generated distributed energy. Then, the optimal model parameters and the capacity of all self-built distributed energy resources are determined by optimizing the parameters of the policy model. In order to promote the implementation of this policy, the government encourages users to build their own distributed energy sources gradually by raising the allowed policy parameters at different stages. Finally, an example is given to verify the adaptability and effectiveness of the proposed model.
