“…In this context, more and more scholars pay attention to promoting the accommodation of renewable energy such as wind power through the coordinated operation of different energy systems, which is worth studying. FANG et al [13] proposed to use electric boiler (EB) with heat storage to participate in peak load regulation of power grid, so that the power grid can accommodate more wind power generation. LIANG et al [14] and LIU et al [15] respectively analyzed the improvement effect of CHP unit and electric boiler equipped with heat storage device on the wind power accommodation capacity of integrated heat-power system.…”

Due to the anti-peak shaving characteristics of wind power under the operation mode of "power determined by heat", a large number of wind power is abandoned at night. In order to solve the problem, this paper proposes a method of coordinated operation of ground source heat pump (GSHP) and combined heat and power (CHP) units. Through indirectly reducing the generation power of CHP units, the accommodation space of wind power in power grid is improved. A two-stage robust optimal scheduling model of regional integrated heat-power system (RIHPS) considering the uncertainty of wind power generation and power load is established. And a distributed solution method based on Alternating Direction Method of Multipliers (ADMM) method and column-and-constraint generation (C&CG) algorithm is designed. Then, the Locational marginal pricing strategy with the goal of guiding users to participate in wind power accommodation is analyzed. The numerical simulation results show that the wind power accommodation capacity of the integrated system under the operation mode of "power determined by heat" can be improved through installing GSHP at CHP units and using price signal guidance.

“…References [8]- [12], which aimed at integrated electrothermal scheduling and considered heat storage and electric heating equipment, provided the additional consumption for distributed generation according to the demand for heat and the characteristics of thermal power plants. These researches proposed strategies which promote the consumption of wind power and diminish the negative effects brought by the aforementioned cogeneration units.…”

Smart grid with great flexibility requirements will not accommodate high proportion of distributed generation with uncertainty in the future. Hence, it becomes indispensable to research scheduling strategy of distributed generation, aiming to reduce serious curtailment of renewable energy. This paper firstly proposes a virtual power supply, which consists of wind power (WP), photovoltaic (PV) power and pumped storage (PS) power. Based on that, a scheduling strategy structure considering stochastic characteristics caused by WP and PV is designed. After that, according to probability distribution of WP and PV, typical virtual power scenarios are obtained via scenario prediction and scenario reduction method. Furthermore, based on flexibility of virtual power and guidance of time-sharing electricity price mechanism, a coordinated scheduling model with optimization objective that maximizes profit is established. Finally, in simulation, validity of proposed model is verified via comparing with different scheduling models. Besides, profits of system under various peak-valley prices are analyzed, which can provide guidance for electricity pricing. The results illustrate that the proposed scheduling strategy can efficiently balance economy and flexibility in optimizing WP and PV consumption and profits of system are increased with 28% at most. INDEX TERMS Coordinated scheduling, distributed generation, photovoltaic power, pumped storage power, wind power, uncertainty.
