“…Another possibility is the participation of customers in virtual power plants to provide reactive energy. [16][17][18][19][20] discusses the provision of reactive power services from DER using a market mechanism and a plan to convert Microgrid into VPP, which is beneficial for consumers, prosumers and utility operators.…”

The resources of active and reactive power for which can be obtained using an AC voltage controller with a phase-angle control for regulation of operating modes of the ohmic load of consumers, for example, distributed systems of electric space heating or electric water heating, etc. A method is proposed and the results of the analysis of the phase-angle control modes by gate turn off (GTO) thyristors of the AC voltage regulator, which provides the generation of virtual reactive power by consumers of active power, are presented. The process equipment of such a virtual power plant is fully suitable both for the dynamic production of a virtual resource of active power to balance, for example, the power of dynamic distributed renewable energy sources (virtual power plant (VPP) mode), and to regulate reactive power to ensure adequate voltage levels and increase stock stability of operation of electric load units (virtual reactive power plant (VRPP) mode).

“…In this way, many aggregated small‐scale DER could effectively be used as a substitute for synchronous generators, not only for energy purposes, but also to provide fundamental system services. Recent developments are also looking into the possibility of creating “hybrid” VPPs from an aggregation of multi‐energy resources, such as those based on electricity and hydrogen, to provide simultaneous network, system and market services (Naughton et al, 2020).…”

“…In particular, PEM electrolysers could provide post-contingency FFR with a speed (almost) compatible with BESS, indicatively within 1-2 seconds. Furthermore, HE PEC interfaces can potentially also allow reactive power control, which can untap the provision of multiple grid services and participation in multiple markets (Naughton et al, 2020). Given the expected growth in the number of electrolysers, particularly for green hydrogen production, and their operational flexibility, there is a great opportunity for this technology to become an important provider of balancing services, and different ancillary services, particularly relating to frequency control.…”

Increasing power system stability challenges are being witnessed worldwide, while transitioning toward low‐carbon grids with a high‐share of power electronic converter (PEC)‐interfaced renewable energy sources (RESs) and distributed energy resources (DERs). Concurrently, new technologies and operational strategies are being implemented or proposed to tackle these challenges. Since electricity grids are deregulated in many jurisdictions, such technologies need to be integrated within a market framework, which is often a challenge in itself due to inevitable regulatory delays in updating grid codes and market rules. It is also highly desirable to ensure that an economically feasible optimal technology mix is integrated in the power system, without imposing additional burdens on electricity consumers. This article provides a comprehensive overview of emerging power system stability challenges posed by PEC‐interfaced RES and DER, particularly related to low inertia and low system strength conditions, while also introducing new technologies that can help tackle these challenges and discussing the need for suitable techno‐economic considerations to integrate them into system and market operation. As a key point, the importance of recognizing the complexity of system services to guarantee stability in low‐carbon grids is emphasized, along with the need to carefully integrate new grid codes and market mechanisms in order to exploit the full benefits of emerging technologies in the transition toward ultra‐low carbon futures.

“…The study of VPP's optimized scheduling also considers the safety of power grid, the flexibility of power system and the practical significance of self-contained power plant. Naughton proposed a scenario-based, uncertain multi-energy VPP operation optimization method that optimizes participation in multiple energy and ancillary service markets while reducing the limitations of local networks and providing reactive support [8]. Coelho presented a network-secure bidding optimization strategy to assist aggregators of multi-energy systems calculating electricity (energy and reserve), gas and carbon bids, considering multi-energy network constraints [9].…”

With the development of renewable energy, improving the absorption capacity of power grid has become a difficult problem. It is very important to establish virtual power plants based on self-supplied coal-fired power plant to coordinate renewable energy consumption, especially in Xinjiang Province, China. This paper studied the optimal scheduling of a virtual power plant including wind turbines, photovoltaic units, and energy storage equipment based on the self-supplied power plant. First, a mathematical model of the power and power generation cost of each unit inside the virtual power plant was established, and the demand response mechanism was introduced. Secondly, a multi-objective optimization model is established by considering the maximization of net income of virtual power plants, the minimization of system coal consumption and the maximization of user interruption load benefits, and the use of analytic hierarchy process to determine the weights of three objective functions, of which user interruption load benefits are used to reflect the enthusiasm of users to interrupt the load. Finally, the particle swarm algorithm is used to solve the model. The optimization results show that when the coal price rises, the net income of the system decreases, and even a loss occurs, however, the change in coal price has little effect on the Interrupted load of user. In addition, multi-objective optimization can improve the enthusiasm of users while ensuring the net income of the system, it proves that the model has a good optimization effect.
