frequency control is essential to maintain the stability and reliability of power grids. For decades, generation side controllers, e. g., governors and automatic generation controllers, have been used to stabilize the frequency of power systems, which incur high operational costs. In smart grids, utilizing demand response is an appealing alternative to control the system frequency at the demand side, which can reduce the dependency of grids on expensive generation side controllers. Despite of economic advantages, the frequency oscillation problem, which occurs when smart appliances simultaneously respond to the system frequency by varying their power consumptions, is the main barrier to realize demand response enabled frequency control in practice. In this paper, we investigate a new distributed control algorithm by randomizing smart appliances' responses to solve this problem. We provide a comprehensive analysis to characterize various impacts of the randomized demand response on the system frequency in terms of its mean and variance over time. Furthermore, based on the frequency dynamics analysis, we determine the average frequency recovery time, the average number of responded smart appliances, and the probability of frequency overshoot, which provide important guidelines for designing our control algorithm. Finally, we validate our analysis via simulations under practical setups.

In this paper, we propose a new distributed frequency control scheme for electric vehicles (EVs) to help restore the power grid frequency upon a contingency of supply-demand imbalance. Under our scheme, each EV independently monitors the grid frequency at discrete times and responds by switching among its charging, idle, and discharging operational modes according to a simple threshold-based switching algorithm. To recover the grid frequency smoothly and prevent an undesired frequency overshoot/undershoot due to simultaneous response of EVs, we design the inter-response times of any EV to follow an exponentially distributed random variable with a certain mean value at each operational mode. To draw insights into the performance of our scheme, we characterize its impacts on the grid frequency in various aspects, including the mean and variance of the resulting grid frequency over time, the mean frequency recovery time, the average number of EV switching their modes, and the probability of frequency overshoot/undershoot. Accordingly, we formulate an optimization problem for the grid operator to minimize the expected cost of implementing our frequency control scheme by designing EVs' response rates subject to their requested incentive prices and the given grid performance guarantees. Finally, we validate our analysis via simulations on the IEEE 9-Bus test system and the Ireland power system, where it is observed that our frequency control scheme can be used as a reliable and cost-efficient alternative for the conventional primary reserve service.

This paper develops a distributed frequency control for renewable microgrids through communication networks subject to disturbances. The proposed distributed cooperative control, consisting of distributed primary control and secondary control, will synchronize the frequency of microgrids to the desired values and through a sparse communication network subject to disturbances, that is to say, considering asymmetric communication delays and noise disturbances. distributed cooperative controllers are designed into the secondary control stage for renewable microgrids, in which manner the criteria for the stability analysis and delays boundedness to maintain the system stable are derived. With the proposed algorithms, control derivation of frequency produced during the primary control stage can be well remedied even if the communication delays and noise disturbances may exist. The effectiveness of the proposed control methodology is verified by the simulation of a renewable microgrid system in MATLAB/SimPowerSystems.

In this work, proof of Authority (PoA)-based Ethereum blockchain is utilized to carry out the peer-to-peer (P2P) energy transactions with an adaptive controller operating in a distributed manner. A federated average learning of recurrent zeroing neural dynamics designed self-adaptive fractional-order proportional integral derivative (FAL-ZND FOPID) controller is proposed for distributed frequency control of networked microgrid (NMG) system. By employing a blockchain-enabled distributed control system and implementing supplementary control, the proposed method efficiently regulates the frequency of P2P energy trading. The contract participation matrix, which facilitates the transmission of energy demand information from consumers to prosumers, is computed as part of the supplementary control. Thus, it provides the power reference signals to prosumers who participate in ancillary frequency services. Overall, the blockchain implementation ensures that the transfer of signals remains secure from cyber threats. To showcase this concept, the prosumer and consumer nodes are established within the blockchain network using Raspberry Pi devices. These devices are then connected to the NMG setup in OPALRT through the socket interface and communicate via TCP/IP protocol.

With more and more distributed energy resources (DERs) deployed in Integrated Energy Systems (IESs), frequency stability challenges the pursuit of reliability and efficiency. This paper proposes a fully-distributed frequency control method for load-side DERs, in which the optimality can be guaranteed in an IES where electricity and heat are coupled. Moreover, the global asymptotic stability of the closed-loop system is proved and the robustness with respect to inaccurate coefficients is shown. Case studies demonstrate the effectiveness of proposed method.

Large networks interconnected by multi-terminal high-voltage direct current (HVDC) systems have become mainstream trend for power system operators. In this paper, the distributed control scheme is proposed to study primary frequency regulation problem in these multi-terminal HVDC systems. Considering the effect of connectivity of areas in the net, we improve the pure PI control inspired by the consensus for the better transient and steady state natures. By using the Laplace transform and the Routh-Hurwitz stability criterion, the stability of the whole system is proved. Finally the numerical examples are used to validate the effectiveness of proposed control scheme.

To tackle the challenges of distributed flexible resource coordination and inherent control delays in virtual power plant (VPP)-participated frequency regulation (FR) for interconnected power systems, this paper proposes a novel distributed model predictive control (DMPC)-based FR strategy with time-delay compensation. A hierarchical FR architecture is first established, incorporating analytical models of communication latency in VPP coordination and detailed electro-mechanical dynamics of generation-load systems. Through state-space augmentation techniques, we develop a delay-embedded generalized predictive model that systematically integrates historical state reconstruction and future trajectory prediction. This approach constructs a time-delay-compensated DMPC (TDC-DMPC) optimization framework that uses quadratic programming to solve the objective function and generate the optimal FR control sequences for VPP flexible load clusters. Comparative simulations on a four-area interconnected power system show that the proposed TDC-DMPC strategy achieves significant progress in frequency regulation. Operating under a 30 ms communication delay, the TDC-DMPC reduces frequency deviations by 30.5% and 18.8% compared to conventional DMPC and sequence-selective DMPC (SS-DMPC), respectively, while reducing the stabilisation time to 0.4 s-a fivefold improvement over the conventional method's 2.2 s. Robustness analysis confirms exceptional resilience, with the system maintaining stable operation under extreme conditions, including 600 ms communication delays and 20% parameter perturbations, significantly outperforming existing methods in stress scenarios.

Overcoming Communication Delays in distributed frequency Regulation

This paper proposes a general framework for determining the effect of communication delays on the convergence of certain distributed frequency regulation (DFR) protocols for prosumer-based energy systems, where prosumers are serving as balancing areas. DFR relies on iterative and distributed optimization algorithms to obtain an optimal feedback law for frequency regulation. But, it is, in general, hard to know beforehand how many iterations suffice to ensure stability. This paper develops a framework to determine a lower bound on the number of iterations required for two distributed optimization protocols. This allows prosumers to determine whether they can compute stabilizing control strategies within an acceptable time frame by taking communication delays into account. The efficacy of the method is demonstrated on two realistic power systems.

This paper describes a fully distributed power dispatch method that can achieve fast frequency recovery and minimal generation cost for autonomous microgrids. The method is comprised of two stages. In the first stage, a subgradient-based consensus algorithm is used to recover frequency. The equal increment rate criteria is incorporated into this algorithm to achieve a minimal regulating cost, obtained by economically distributing power among distributed energy resources. control signals updated with latest local measurements are executed in each iteration step to speed up the frequency recovery procedure. In the second stage, an average consensus algorithm is applied to resolve frequency oscillations caused by measurement errors. Numerical tests are described to demonstrate the validity of the proposed method and its applicability in the presence of communication time delay is discussed.
