Special Issue Information
Dear Colleagues,
In power systems with a high proportion of renewable energy, the problem of wind and light abandonment is becoming more and more prominent as the total installed capacity of wind power and photovoltaic continues to increase. Due to the limited accuracy of wind power and PV output prediction, the randomness of their output will cause a certain impact on the power grid. The integrated energy network and microgrid system can use the surplus power of new energy to produce hydrogen and store it or use it for downstream industries; when the load of the power system increases, the stored hydrogen energy can be fed back to the grid using fuel cells to generate electricity, and the process is clean, efficient, and flexible.
Integrated energy networks and micro-grid systems are the future direction of multi-energy utilization, covering various forms and characteristics of multienergy, such as photovoltaic, wind power, fuel cell, etc., and various forms of energy storage systems and devices, such as lithium battery, super capacitor, electrolytic tank, etc., in order to realize the integration of electricity, gas, heat and other complementary multienergy, but also to realize the source network, load, and storage of the whole link highly coordinated and flexible interaction, centralized and distributed combined with each other.
Further, the power system requires power generation and grid load demand to achieve transient balance, but with the landscape and other grid-connected new energy generation and demand-side resource ratio increases, its strong volatility and high uncertainty significantly increase the probability of power imbalance in the grid and seriously limit the grid to renewable energy consumption capacity, resulting in the phenomenon of “wind and light abandonment”, which is particularly frequent. At the same time, in the pursuit of its consumption capacity, without sufficient feasible technical support, a high proportion of renewable energy access to the grid may cause line overload, loss of load, static voltage instability, and other risks, making the power system face serious security problems. In essence, it is a requirement and challenge for the overall control architecture and renewable energy consumption mode of integrated energy networks and microgrids.
The purpose of this Special Issue is to collect research papers and reviews on “Integrated Energy Networks and Microgrids” to reflect the latest trends and challenges in this topic. The scope of this Special Issue includes high-precision modeling, dynamic and static analysis, and optimal control methods for integrated energy networks and microgrids, as well as research on microgrid performance evaluation and fault diagnosis algorithms.
