## 1 Introduction
Per the significance of thermal effect concerning the integration of the DERs grid, expertise is encouraged to develop effective, low cost, and viable monitoring systems for small and medium scale Distributed Generations (DGs) to ensure optimal performance [13]. Thus, the wireless communication network is an emerging technology that integrates WSNs and mobile computing with transducers to perform sensor platform topology [14; 15]. The integration of computing techniques and Radio Frequency (RF) has dominant features. The design concept explores LM35 temperature sensors to measure the thermal conditions of the system and archives them at the Data Management Unit (DMU) of the Distribution Management System (DMS). The performance provides the state assessment of DERs behavior in order to respond timely, should abnormal conditions occur [16]. Therefore, the reliability of the entire system is assured in times of critical network situations. The thermal effect when not monitored restricts the system's power delivery, as temperature profile rises excessively. It then reaches a critical state of condition, destroying the distribution network components [17; 18]. It further affects system configuration performance when the demand side operates beyond the threshold capacity. The scope of the study is to develop a concept to synthesize the thermal behavior of DERs integrated network comprising solar PV panels, wind turbine compartment, distribution cable lines, protection control components, and storage batteries with inverters. The concept seeks to leverage system real-time monitoring of temperature profiles. It uses sensor operating techniques and softwarecomputing with ZigBee communication link and also transmits abnormality through GSM protocol. Should the temperature experience out of range threshold, the system sends an SMS notification to the DMU. The alert details the characteristics of the unit elements in such a condition. The design configuration involves wireless sensor monitoring, data acquisition, and transmission data storage with abnormal threshold conditions alert for activation of control solutions. The alert activation for control solutions could be configured to regulate system intelligence to actuate control schemes applicable for remedial actions during abnormal temperature scenarios. The control schemes may be configured to control system functions for solar PV panels cooling in the case of extreme temperature effect and for cleaning dirt accumulation on the panels. Again, the control scheme can be assigned to operate the cooling system in the protection control unit to solve high-temperature issues. Further, the scheme functions can be programmed to activate reactive power injection should the thermal impact affect power delivery. The design concept has been developed and simulated with Proteus 7.9. The concept design was coded and analyzed in two parts for simulations in the algorithm and circuit development. The algorithm simulation passed a four stages test and the circuit development was successful in the assigned simulations. The exercise randomly selected temperature values for the test threshold configuration and system operation measuring data. The outcome of the performance of the simulation is captured and presented in Section 4. The ZigBee communication link operates per the Institute of Electrical and Electronic Engineers (IEEE) standard protocol 802.15.4. The paper is arranged, in the following order: Section 2, discusses the importance of thermal condition monitoring, Section 3, handles the development of thermal condition monitoring system, Section 4 deals with the system configuration and performance analysis, and Section 5 concludes the study.
