Electric Network Topology and method of transmission of Electric energy
Power engineering: research equipment technology, 2019Co-Authors: N. I. Smolentsev, L. M. ChetoshnikovaAbstract:The purpose of the work is to reduce losses and increase energy saving in Electric Networks. To achieve this goal, a multilevel Topology of the Electrical Network and an asynchronous method for transferring Electrical energy between nodes including a load, energy sources, energy storage devices connected in an appropriate manner are proposed. It is shown by the mathematical method that this Network Topology allows using energy storage devices controlled appropriately and using tele-information technologies to optimize the balance of Electric energy in the Network, achieving equality of the generated and consumed Electricity. Such a Network Topology and a method of transmitting Electrical energy can be the basis of digital technologies in the energy sector (ENERNET).

Study on Adaptive Protection Technology for Shipboard Power System
2011Co-Authors: Zhang XiaofengAbstract:With the development of warship power system,system configuration,Electric Network Topology and operating pattern has change a lot.The three-stage relay protection cannot satisfy demands,which has the feature of off-line setting.Based on the characteristics of traditional protection method,adaptive protection schemes for warship power system are proposed,which adjust protection settings using Network Topology and system state automatically to improve sensitivity and selectivity.

Risk Assessment for the Amount of Transmission System Usage Penalties via Probabilistic Load Flow
2020 International Conference on Probabilistic Methods Applied to Power Systems (PMAPS), 2020Co-Authors: Andre Milhorance, Armando M. Leite Da Silva, Érica Telles, Alexandre StreetAbstract:This paper proposes a probabilistic load flow (PLF) based approach, via Monte Carlo simulation (MCS) and cross-entropy (CE) method, for evaluating possible risks associated with contracting the amount of transmission system usage (ATSU). Distribution companies (DISCOs) and the Brazilian ISO establish these contracts on yearly bases. The application of PLF via MCS-CE provides a risk assessment analysis tool to adequately manage possible penalties due to over/under ATSU contracting when several uncertainties are taken into account. The proposed tool is applied to Brazilian DISCOs considering uncertainties on demand, generation, and Electric Network Topology, i.e., contingencies on transmission elements.

Optimal power flow with transmission switching for power system with wind/photovoltaic generation
2017 Chinese Automation Congress (CAC), 2017Co-Authors: Jiayin Jiang, Xueshan Han, J. Wang, Xingxu Zhu, Donglei Sun, Ma YanfeiAbstract:For the randomness and asynchronous characteristics of wind power and photovoltaic (PV) generation, large-scale integration of renewable generations into power grid, especially when the Electric Network Topology is fixed, has brought the problems of transmission congestion and voltage security in power system operation. In order to make better use of existing Network to promote security and economy of power system, this paper proposes an optimal power flow with transmission switching for power system with wind and PV generation integration. By making full use of the time-domain complementarity characteristics of wind/PV generation, the mathematical model of optimal power flow (OPF) with transmission switching is constructed based on alternating current (AC) power flow to ensure voltage security and improve flexibility of power system operation. Then a combination of genetic algorithm (GA) and the nonlinear primal-dual interior point method is proposed to solve the proposed model. Finally, case studies on a realistic system demonstrate the feasibility and effectiveness of the proposed method.
