摘要：AbstractDemand-side management, involving energy efficiency, demand response, and distributed generation, is an efficient and effective way to improve the security of electricity via changing the profile of power demand, but portfolio management of these resources still lack systematic and comprehensive investigation. In this paper, a optimization-based framework of demand-side management is proposed, with resource optimization at the bottom level and portfolio optimization at the top level. Resource optimization is modeled in terms of energy efficiency, demand response, and distributed generation. Portfolio optimization is also generalized into four categories, and for each category an instance of application is studied. Reported results shown that the portfolio approach is essential to reach full potential of demand-side resources and to achieve the best energy and cost savings.
