“…In order to give a recommendation for system planners, the question about the excess electricity has to be answered: If everything is to be stored with daily storage, a PV-based system could have advantages. In contrast, if it turns out that daily storage is too expensive and there are other solutions like power-to-heat [23] or power-togas, a mainly wind-powered system with about 20e30% of PV generation is the best solution for a system with very high shares of VRE in China.…”

“…As a consequence, flexibility provided by storage or DSM (demand-side-management) will be required to integrate more renewable generation, which was examined for China e.g. by Chang et al [23]. In order to keep integration costs at a low level, it seems beneficial to find a mix between wind and PV that minimizes the hourly oversupply while reducing the peak power and the annual generation of remaining conventional sources.…”

“…We assume that in scenarios with a being larger than 0.6 other technologies would help in the balancing challenge which could be a large scale DSM with sector coupling with heating and transportation as described, for instance, in Ref. [23] for China.We therefore focus on the findings for a < 0.6 and consider the storage criterium as another reason for combining the sources e wind and PV e to a hybrid renewable system.…”

A large amount of wind power has to be curtailed due to the inflexibility of the combined heat and power (CHP) system in the heating season in northern China. The power-to-gas (P2G) technology, which uses electricity to produce hydrogen or synthetic natural gas, has become a promising energy conversion option for the utilization of surplus power energy. In this paper, an integrated natural gas, heat, and power dispatch (INGHPD) model which balances natural gas, heat, and power demand considering wind power and a P2G unit, is proposed. A natural gas network and P2G are modeled and integrated into the dispatch model. To demonstrate the effectiveness of the proposed model, an integrated energy system consisting of a six-bus power system, a six-node natural gas system, and a district heating system is simulated. The benefits of P2G are investigated in terms of reducing wind power curtailment, as well as system operation cost and CO 2 emissions. The results in the deterministic model show that with the introduction of 40 MW P2G, the wind power curtailment rate decreases from 24.0% to 9.7%. The daily wind power energy consumed by P2G reaches 256 MWh and the daily CO 2 emissions reduction reaches 46,080 kg. Additionally, the impact of the power and heat demand on the gas production of P2G and of the P2G capacity on the wind power curtailment are also investigated. P2G tends to generate more natural gas when the power demand is low and the heat demand is high.

The combined heat and power system (CHPS) is one important type of the integrated energy system in Northern China. Compared with the independently operated power system, the combined heat and power system (CHPS) has a great potential to improve the utilization of wind energy in virtue of the energy storage of the heating system and power‐to‐heat (P2H) devices. This paper studies the optimal operation of the CHPS equipped with the electric boiler (EB) and heat pump (HP). Comprehensive factors are considered, including P2H conversion, the thermal inertia of district heating network (DHN) and buildings, and adjustable heat loads. An equivalent model of the heating system is developed to express the direct mathematical relations between the heat source and heat loads. Redundant details of the DHN are simplified to reduce the complexity of the optimization problem. Furthermore, a self‐repair method incorporated with the real‐coded genetic algorithm (RCGA) is proposed to efficiently handle the nonlinear constraints. The effectiveness of the solving method is verified in case studies. The impacts of the EB and the HP on the CHPS are compared in details. The results show that the HP offers better performance than the EB on coal saving and improving wind power integration.
