State Estimation in Low Voltage Grids Based on Smart Meter Data and Photovoltaic-feed-in-forecast
The integration of distributed generation causes an increase of the voltage magnitude in low voltage grids. In addition to classical grid expansion distribution system operators have various options at their hands to reduce the voltage rise, e.g. by installing distribution transformers with on-load tap changers or voltage regulators. But for efficient control the network operators need informat...
متن کاملField Test of a Linear Three-phase Low Voltage State Estimation System Based on Smart Meter Data
The area-wide installation of smart meters in low voltage (LV) grids prospectively provides information about the relevant operational system parameters, e.g. complex node voltages and line loads. Under the condition of neglected house to grid connection lines, a positive local measurement redundancy at every network node is obtainable. In general, this enables the implementation of special thr...
متن کاملPic Microcontroller-Based Automatic Meter Reading (AMR) System Using the Low Voltage (LV) Power Line Network (TECHNICAL NOTE)
Automatic Meter Reading (AMR) is the remote collection of consumption data from customer’s utility meters over telecommunications, radio, power line and other links. AMR provides water, electric and gas utility service companies the opportunity to streamline metering, billing and collection activities, increase operational efficiency and improve customer service. The AMR system consists of thre...
متن کاملLow-Voltage and Low-Power CMOS Voltage-to-Current Converter
A CMOS voltage-to-current converter in weak inversion is presented in this Letter. It can operate for low supply voltage and its power consumption is also low. As the input voltage varies from −0.15 V to 0.15 V, the measured maximum linearity error for the proposed voltageto-current converter, is about 3.35%. Its power consumption is only 26 μW under the supply voltage of 2 V. The proposed volt...
متن کاملAn Ultra High CMRR Low Voltage Low Power Fully Differential Current Operational Amplifier (COA)
this paper presents a novel fully differential (FD) ultra high common mode rejection ratio (CMRR) current operational amplifier (COA) with very low input impedance. Its FD structure that attenuates common mode signals over all stages grants ultra high CMRR and power supply rejection ratio (PSRR) that makes it suitable for mixed mode and accurate applications. Its performance is verified by HSPI...
