This approach takes into account several factors, including the benefits of participating in demand response, the costs associated with consumer dissatisfaction, the costs of power purchased from the electricity market, the costs of renewable power purchased from the green power market, and the costs of carbon emission permits purchased from the carbon market. The two-step formulation establishes an equilibrium problem with equilibrium constraints. A chance-constrained optimization method is utilized due to the uncertain fluctuation of renewable power in the two steps. The equilibrium problem with equilibrium constraints in the two steps can be settled by the nonlinear optimization of multiple subproblems with corresponding Karush-Kuhn-Tucker conditions.

A meaningful optimal placement of Phasor Measurement Unit (PMU) for substation oriented complete system observability and Phasor Data concentrator (PDC) have been ensured proposing new method for solving Integer Linear Programming (ILP) using General Algebraic Modelling Language (GAMS) platform. Critically important location vector have been formulated applying Multi Attribute Utility Technique (MAUT), which directs the PDC deployment location selection. However, only the optimal distribution of PMUs and PDCs throughout the network does not satisfy the purpose of these sophisticated yet costly measuring and monitoring devices; rather it is required to be ensured that the fast and precise measurements from this device can be reached to the generation and transmission operators via PDC through the shortest communication path. Hence, a shortest spanning path algorithm has been proposed for the minimization of the communication path among the WAMS elements. The proposed method has been extended while the cyber physical attack compromised device is present in the system. The empirical WAMS elements communication network has been modelled and executed in OMNeT++. The overall cost is calculated by considering some practical cost of the WAMS elements. The efficacy of the proposed technique is checked applying by it on standard IEEE test cases- IEEE 14 bus, 30 bus, and 118-bus system, and represented with post mortem analysis.

This paper presents a bi-level optimization framework based on location marginal pricing settlement of mobile energy storage financial rights revenue in active distribution systems. In the developed framework, the upper-level problem determines the optimal capacity, routing, and dispatching of mobile energy storage to maximize revenue in the liberalized electricity market. The lower-level problem performs the joint optimization of energy and reserve market clearing as well as renewable energy capacity optimization based on the alternating current optimal power flow model.

Aiming at the above problems, this paper proposes an aggregated regulation and coordinated scheduling method of PV-storage integrated 5G BSs considering PV-load uncertainty. Firstly, a hierarchical cluster-cooperative aggregated regulation framework for the scale PV-storage integrated 5G BSs is established, and a regional communication operator (RCO) schedulable capability model and an information gap decision theory (IGDT) based PV-load uncertainty model are built. Next, a two-stage joint optimization problem is proposed for maximizing the RCO income while reducing the BS cluster operation cost.

The proposed method aims to minimize the cost of PMU and DULR configuration. Based on the known pseudo-measurements and Supervisory Control and Data Acquisition (SCADA) measurements, we use the E-optimal standard design of the state estimation error covariance matrix to form the state estimation accuracy index and take the relay protection function of Feeder Terminal Unit (FTU) device and DULR device into consideration of the fault reconstruction. By solving the mixed integer semidefinite programming (MISDP) model, the optimal placement result is obtained, so that the network under normal condition and the network after multiple fault reconstruction can meet the constraints of state estimation accuracy and load loss rate respectively. The proposed method is tested on IEEE 33-node, 123-node systems as an example. The experimental results show that the proposed method is effective and practical.</div><div><strong><em>Note to Practitioners—</em>This study is stimulated by the need for optimizing the placement of Micro-PMU (µPMU) in distribution network. Since the new µPMU device DULR has the same relay protection function as FTU, and distributed generation can supply power to the island after failure, this paper adds the load loss rate to the constraint conditions to study the influence of fault reconstruction on the placement scheme. A new two-step SE method considering mixed measurements was used in this paper to improve the computational efficiency of real-time SE of large-scale system while ensuring the accuracy of the calculation results. We have conducted tests in IEEE-33 and IEEE-123 systems. After preliminary verification, compared with the single fault scenario, we find that the placement scheme considering multiple fault scenarios can effectively improve the accuracy of state estimation and reduce the load loss rate of each fault scenario and only increase the cost a little. The increase in the number of DG and contact lines in the network will also effectively improve the feasibility of the placement scheme.

This paper proposes a novel strategy with a low cost for solving this problem.

Also, in this paper, a new topology of DC/DC converter with a controlled zero-current output function is proposed for fast switching off the paths of DC short-circuit current components from DG branches to the fault point.
