DEVELOPMENT OF A SEARCH ALGORITHM OF CONTROL NODE VOLTAGE LEVELS ENSURING ACTIVE POWER FLOW BALANCE REDUCTION IN A CONTROLLED SECTION

Abstract

The article deals with the development of a search algorithm of voltage levels and transformation coefficients of measure points under which the increased value of the net power flow of the active power reduces in the controlled section that allows to minimize the volumes of introduced restrictions of power supply. METHODS. The algorithm is based on electric mode optimization by the reduced gradient method featuring the target optimization function represented by the function that reflects an inadmissible exceedance of the active power flow balance in the controlled cross-section. The algorithm is implemented in PTC Mathcad. RESULTS. On example of the model of a six-node electric network synthesized in the PTC Mathcad we showed a 3.64% reduction in the active power flow balance through the use of the developed algorithm. CONCLUSIONS. It has been found out that voltage regulation in the measure points allows to reduce the values of the active power flow balance in the cross-section and minimize the voulumes of introduced restrictions of power supply required to enter the active power flow balance in the range of permissible values.
