As competition increases, companies are demanding more services from their ad-agencies. Hence, ad-agency-client relationship is more prone to stress and strain than ever before. There is no single factor which cements a strong bond between the agencies and the clients. It's a multitude of them, which makes it difficult to pinpoint a particular aspect which could be responsible for making or breaking an agency-client relationship. A client does not approach an agency only because it produces creative stuff or it has media strength. The good relationship between ad-agency and clients mainly depends on the appropriate selection of an agency by the clients and correspondingly, on a high degree of accountability by the agency to the clients. Once such sustainability has been established through the selection process, initial adjustment, mutual respect and responsiveness the relationship will go on for many years without any disturbance. But, present scenario of relationship between these two not upto the expectation because different advertisers (clients) have different needs, but one factor that unites today's clients is that they all demand accountability for the money spent on advertisement by the ad-agency on creation and delivery of advertisement. This means a quantum change in the industry affecting the traditional agency-client relationship. Loyalty and tradition no longer derive choice of an agency. Instead, return on investment makes up the bottom line. Clients are constantly evaluating the work of their agency and its rival. This article critically examines the relationship binding and breaking factors between the ad-agency and their clients by taking into consideration of the following two parameters, viz. the clients' expectation from the agency and the level of satisfaction and the ad-agency's expectation from the clients.

This paper presents a standalone hybrid renewable energy system (SHRES) to supply alternating current (AC) loads. The interfacing configuration of SHRES sources to the AC bus is discussed. The control strategies based on voltage and frequency (Vf) with droop concept for the stable source and active and reactive (PQ) power control concept for the energy sources are proposed for the SHRES’s stability, power quality and load sharing. The SHRES and the control strategies have been modeled in PSCAD/EMTDC software. Simulation results show the proposed control strategy is shown to be able to regulate the voltage and frequency at the common AC bus.
