Optimal Operation and Management of Smart Grid System with LPC and BESS in Fault Conditions

Abstract

Distributed generators (DG) using renewable energy sources (RESs) have been attracting special attention within distribution systems. However, a large amount of DG penetration causes voltage deviation and reverse power flow in the smart grid. Therefore, the smart grid needs a solution for voltage control, power flow control and power outage prevention. This paper proposes a decision technique of optimal reference scheduling for a battery energy storage system (BESS), inverters interfacing with a DG and voltage control devices for optimal operation. Moreover, the reconfiguration of the distribution system is made possible by the installation of a loop power flow controller (LPC). Two separate simulations are provided to maintain the reliability in the stable power supply and economical aspects. First, the effectiveness of the smart grid with installed BESS or LPC devices is demonstrated in fault situations. Second, the active smart grid using LCPs is proposed. Real-time techniques of the dual scheduling algorithm are applied to the system. The aforementioned control objective is formulated and solved using the particle swarm optimization (PSO) algorithm with an adaptive inertia weight (AIW) function. The effectiveness of the optimal operation in ordinal and fault situations is verified by numerical simulations.

Optimizing Battery Energy Storage System Data in the Presence of Wind Power Plants: A Comparative Study on Evolutionary Algorithms

“…Additionally, the Pareto optimal front (POF) was employed to obtain the global solution of simulating an IEEE 30-bus system. Furthermore, Shigenobu et al [23], have addressed a decision framework for optimal programming of a BESS connected to a distributed generation (DG) with an inverter and voltage control instruments. To be more detailed, a two-step simulation was considered, including the effectiveness of the BESS, which was connected to the smart grid (SG) under fault conditions, and the active SG using LPC (loop power flow controller) was proposed by applying the PSO algorithm to optimize the relevant objectives.…”

A Countermeasure for Preventing Flexibility Deficit under High-Level Penetration of Renewable Energies: A Robust Optimization Approach

“…However, such a sudden shift in the energy mix can worsen the conditions of the power system, because renewable energy sources are quite volatile [3,4]. Therefore, some countermeasures are required, including strengthening the grid through investments in the facilities and preparing strategies for the effective operation of renewable energies [5][6][7][8].…”
