“…The formulation captures the basic dynamic features of governors and adds a linear ramp rate constraint to the underlying optimization problem. The concept of simplifying dynamic representations of frequency stability has been extended to various other problems, such as Unit Commitment (UC) [45], storage integration [46], wind turbine frequency response [47], stochastic scheduling [48], and inertia and frequency response pricing [49]. However, in the aforementioned coupled reserve and energy formulations, the system dynamics (i.e.…”

Moving towards low-carbon electricity systems through the massive deployment of renewable energy sources (RES) presents a unique opportunity to combat climate change, but it also poses enormous technical challenges, especially from a frequency viewpoint. To ensure a secure RES integration in terms of frequency stability, system operators worldwide have adopted new grid codes requiring RES to provide fast frequency response (FFR). However, if not properly justified, stringent requirements may pose an unnecessary barrier to further RES development and slow their network integration. In this context, this paper presents a methodological framework for systematically defining FFR requirements for RES to ensure system frequency stability. The proposal comprises: i) a model for simulating the dynamic response of system frequency following a contingency with reduced computational effort, ii) a model for reallocating contingency reserves with economic criteria to avoid loss of load following a contingency, and iii) novel indices for characterizing the dynamic performance of system frequency in terms of key operational characteristics, which are then used for defining frequency related grid codes. The benefits and practicability of our proposal are demonstrated in a case study on the Northern Interconnected System in Chile. We show how our proposal can be used to i) identify system operating conditions in which the contribution of RES with FFR is necessary to avoid loss of load and ii) to propose a technically and economically justified grid code that allows both to foster further RES integration while ensuring power system security.

“…The inverter has no inertia and damping characteristics and has a weak ability to adjust system fluctuations [14,15]. Renewable power generation has low inertia and results in serious frequency fluctuations [16][17][18]. The instability of the system limits the power transmission capacity [19][20][21][22].…”

This study constructs a novel virtual synchronous generator system based on a transfer function, and optimizes the parameters of the model by using the improved whale algorithm to improve the frequency control ability of virtual synchronous generator. Virtual synchronous generator technology helps to solve the problem that the integration of large-scale renewable energy generation into the power system leads to the deterioration of system frequency stability. It can maintain the symmetry of grid-connected scale and system stability. The virtual synchronous generator technology makes the inverter to have the inertia and damping characteristics of a synchronous generator. The inverter has the inertia characteristics and damps to reduce the frequency instability of high penetration renewable energy power system. The improved whale algorithm is efficient to find the best combination of control parameters and the effectiveness of the algorithm is verified by microgrid and power system. The results show that the proposed frequency coordination control scheme suppresses the frequency deviation of power system and keep the system frequency in a reasonable range.

“…The remarkable gaps in the literature are outlined as follows: In refs. [5‐15], BESSs have been applied as static sources into power systems for multiple goals, and the mobility capability of BESS in decreasing lines congestion and minimizing operational cost in the transmission‐constrained scheduling has been neglected. In refs. [16‐22], although the mobility capability of BESS has been deployed in the UC, they have not comprehensively investigated economic, technical environmental assessment of BESTrain under a multi‐objective framework.

Summary By increasing environmental pollution and the energy crisis, the development of renewable energy sources (RESs) has become an essential option to ensure a sustainable energy supply. However, the inherent uncertainty of RESs poses significant technical challenges for independent system operators (ISOs). Transmission line congestion has become one of the significant challenges for ISOs to use the maximum power of RESs. The mobile battery‐based energy storage systems can provide a promising solution for the transportation of the generated energy from RESs to load centers to mitigate the effects of line congestion on the power network operation. Hence, this article evaluates the impact of battery‐based energy storage transport by a train called BESTrain in a unit commitment model from the economic, environmental, and technical aspects under a multi‐objective mixed‐integer linear programming framework. The uncertainties associated with wind power and electric demand are also handled through a two‐stage stochastic technique. The main aim of the introduced model is to minimize the carbon emission and operational cost simultaneously by determining the hourly location and optimal charge/discharge scheme of the BESTrain, and optimal scheduling of power plants. The numerical results exhibit the reduction of operation cost and carbon emission by 6.8% and 19.3%, respectively, in the presence of the BESTrain.
